Without an ozone layer this cell would receive heavy doses radiation from the sun- obviously this would kill it. In addition to all of the other excellent responses in this thread, Dosing of the first cell or pre-cells with radiation would have increased mutation/breakage/rearrangement rate in the nucleic acids of those cells, thus potentially accelerating evolution.

life can not be created -ocationally- by chemical reactions -ONLY-.in the very short age of earth to be so. There must be a reason -the same first reason - that created the whole univerce before.Is not it true???!!!

life can not be created -ocationally- by chemical reactions -ONLY- I have no idea what 'ocationally' means. However taking just 'life can not be created by chemical reactions' this statement is demonstrated false every single time anything reproduces. There is nothing mystical about life; it's just chemistry in action.

"You answered this in the first part of your paragraph - the ocean protects it, if it's deep enough."
"Dosing of the first cell or pre-cells with radiation would have increased mutation/breakage/rearrangement rate in the nucleic acids of those cells, thus potentially accelerating evolution." pink sasquatch, you and crashfrog have different arguments

tubi417 writes: pink sasquatch, you and crashfrog have different arguments They are two different, though related, arguments. One points out that because the radiation doesn't penetrate deeply through water, increasing depth provides increasing protection from it. The other points out that the greater the radiation, the greater the mutation rate, potentially accelerating evolution. You can combine these two arguments to conclude that the deeper an organism resides in the ocean, the slower its rate of mutation due to radiation. --Percy

quote: 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.

Tubi-
Crashfrog and I do not contradict each other's arguments. See Percy's message #21 - it is clear and concise.

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).

Would you care to present the mathematics that leads you to that conclusion? I'm curious to know since we don't have a definite path for the origin of life, I can't really see how you could possible calculate it's probability.

let us begin step by step
but first, I would like to know if you beleive that life had been created without a creater.!!!!

Yes, I do.

Imagine with me please .
the earth is born having elements and some simple compounds.most of it is water . atoms are moving colliding with each other, combining ,forming a large molecule such as proteins (which will play a great role in life -later-)how long -do you think- such a procces will take? then a molecule with an another and another gathered to form a primary cell. what make a molecule rather than the others to be a membrane to protect the cell from outer conditions??!!! can you tell ?? now this living cell found that it must do some procceses to keep living !!okey .reproducing! how could a mindless molecules know how to divide the cell into two similar cells??!how to know what essential components must exist in both to keep living??!!!!do you want me to continue??
