pink sasquatch, you and crashfrog have different arguments
And their arguments vary as wildly as the theories regarding abiogenesis. There are quite a few pathways that have been suggested, but at this time it is hard to tell which is right. What we do know is that the chemistry that occurs in the human body, or within any organism, is no different than the chemistry you did in high school. There is nothing special separating the worlds of inorganic chemistry and organic chemistry. There is nothing separating the chemistry of life from the chemistry of non-life. In other words, there is no reason that life COULD NOT HAVE arisen from non-life. What scientists are working on now is the plausibility of certain pathways. I am confident that scientists will create life from non-life at some point, but I will freely admit that this is personal belief not supported by any evidence.

Re: your topic is logical
quote:
If we accept that life had been exist due to some chemical reactoins ;we -surely-will face the truth that the earth age is too short to be enough .Such reactions (that can creat a such various complicated organisms)will take many many multiples of earth time (if it could be realy).
Why should we only consider Earth in our calculations? Shouldn't we also calculate the chances for the rest of the Earth like planets in the Universe? I will use two analogies to try and make my point clear.
Analogy One
Being that you are from Jordan, you may not be familiar with the Lottery here in the US. In this gambling game, you buy a ticket for one dollar. On this ticket you get a combination of 6 numbers between 1 and 46 (using a simplified lottery, ignoring the Powerball for now). They then number 46 balls and pull them out at random. If your numbers and the numbers on the ball match, then you win millions of dollars for your 1 dollar investment. The chances of this happening are about 1 in 60 million. A pretty small chance. Yet, many people have won this lottery. However, given that millions of tickets are sold the chances that somebody will win is almost guaranteed.
However, let's pretend that five people in my lab by a ticket each. The chances of any of us winning are 5 in 60 million. Guess what, we win. This should be impossible. However, given that there are so many tickets sold SOMEBODY should win, and anybody will do. This is how it is with only focusing on life developing on Earth. People claim that the chances are astronomically high. However, there are many other "ticket holders" out there in the universe. Let's say that the chances of life arising on earth is one in a trillion. Let's also pretend that only 0.001% of solar systems are capable of sustaining life. There are about a billion stars per galaxy, and about a billion galaxies. So there are a billion billion solar systems. 0.001% of a billion billion is a million billion (1015 solar systems). If the chances are a trillion (1012) to one for life, then there should be 1,000 planets with life in the universe. Earth just happens to be one of those winners. Of course, the chances of life arising and the fraction of systems capable of sustaining life are still unknown, but I think those are workable numbers.
Analogy Two:
What are the chances that you were born in the exact city or the exact hospital you were born in. Pretend that there about 1 million hospitals and midwifes in the world. You have a 1 in 1 million chance that you were born with a certain midwife present or in a specific hospital. Those chances are so high that I could state that you shouldn't have been born. However, you were born so the chances are 1 in 1, or a positive fact. Life is the same way. Out of the millions or billions of planets capable of sustaining life we just happen to be on Earth. No matter what the odds are, we are here, it is a fact. So far, no one has shown life arising through supernatural causes, but we have seen life continue and prosper through natural means. Within science, the natural means are the one's studied. Honestly, the truth could be found in the supernatural, but natural mechanisms are sufficient for explaining the emergence of life on this planet.

Evolution is only observed in your mind, not in science.....
Repeat to prove!!!!!!
Sorry Nasa, there have been multiple instances of observed evolution. There have been numerous observed speciation events. Science has recorded numerous beneficial mutations. Science has observed numerous occasions of beneficial mutations being spread through a population. Science has also found concrete evidence of common ancestory between divergent species, such as pseudogenes and ERV insertions. What objective evidence do you have which supports creationism? It seems that you are projecting the weaknesses of the religious creationist movement onto a well supported and well practiced field of science.

Re: I’m no scientist so let me try to put this in laymen’s terms
quote:
a) A, very basic, cell wall can form on it’s own.
b) The simple building block of the genetic code can form, under the right condition, with out intervention.
c) These, pre genetic code strands can copy them selves.
I think, in general, we can all agree with this definition.
quote:
Now, lets apply these to another scenario vary similar to yours.
Let’s take the HP Laptop I’m writing this letter on.
Under the right conditions we can see that some of the same metals mix together in, somewhat, the same way as they are found in the material found in this laptop.
HP laptops aren't a product of nature, nor do they reproduce. Secondly, it is not possible for an HP laptop to naturally form. However, it has been shown that the chemicals needed for life do spontaneously form without outside intervention. Also, some of these chemicals ARE capable of catalysing chemical reactions. Therefore, observations, not fantasy, have led science towards plausible pathways for abiogenesis.
quote:
Each time I go to one of these discussion boards, any one who question’s evolution is called stupid, or worse, and ridiculed for having ‘faith’.
I try not to ridicule anyone, and especially not their faith. However, we do see quite a few basic misconceptions that most creationist or laymen make. For instance, this thread deals with abiogenesis, not evolution. Abiogenesis is a theory within chemistry while evolution requires that life first be present and is found within biology. For evolution to work all you need is an imperfect replicator. It doesn't matter where it came from or how it got there, all that matters is that life was present. If the first life was bacteria planted by space aliens the theory of evolution would be unaffected. However, abiogenesis is a separate theory and makes statements about where life first came from and how it arose. It is best not to confuse the two since there are obvious differences between the two theories.
quote:
‘Windows’ is a far less complicated program then the simplest DNA strand we see in nature. Is it not?
They are about equal in length, but Windows is much more complex. Also, you are equating DNA sequences that we see TODAY and extrapolating them back into the past. This is not accurate nor logical since the first life to use DNA may have been much simpler than anything we see today. Also, the first life may not even have used DNA. The first life may have used catalytic RNA, proteins, or a combination of the two. All you need is a chemical that makes more of itself and voila, you have started life.
quote:
You don’t expect me to believe my laptop evolved {I.E. with no intelligent design}. Do you.
Of course not, because laptops don't make more of themselves. For evolution to work you need reproduction, therefore laptops are not analogous to life.
quote:
If my laptop, as simple as it is {compared to a single cell} could not have come into existence with out thousands, if not hundreds of thousands, of man hours of intelligent designers, then why do you insist that a living cell can come in to existence with out intelligent design?
Because of the natural algorithm of natural selections and mutation. This causative forces cause increases in complexity and information within reproducing populations. A fair analogy would be comparing a reproducing population to a reproducing population. You have yet to do this.
quote:
So, if we are to believe, have faith in, evolution we must be willing to believe that all thing that show both organization, and complexity could come into existence with out intelligent design. After all the most organized, and complex thing in this universe, a single cell, did.
It doesn't require faith. In fact, abiogenesis and evolution don't even require you to believe in it. It stands by itself on the strength of objective evidence. Whether or not you believe that men landed on the moon has nothing to do with the fact that the evidence supports the moon landings. We have never seen life intelligently designed. We have never seen a supernatural deity shuffle DNA. However, we have seen random configurations of atoms derived from earth like conditions cause self catalyzing reactions.
[quote]Sorry, That take[s] more blind faith then I have.[/quote]
Good thing that science doesn't rely on faith. Also, what takes more faith, observations of natural phenomena that can result in self catalyzing reactions or faith in a supernatural deity that has never been evidenced? Would you be the type of person to credit Thor for producing thunder because you feel that swirling hailstones could not possible create the sound?
