Again you are simply making assertions.
​
First, over the billions of years the Earth has existed, the speed of rotation has changed. It is changing even now.
​
In 1754 Kant predicted that friction with the tidal forces on earth would cause a deceleration of the earth's rotation, but it took more than a century before Ferrel and Delaunay could confirm this effect. The secular decrease of the rotation rate causes an increase of the length-of-day of about 2 milliseconds per century.
This value can be determined by comparing the observations of eclipses of the sun and the moon by the Babylonians, Greeks, Arabs and Chinese with computed eclipses when using a constant rotation rate. At present also fossiles and paleomagnetic data are used to determine the increase in length-of-day.
Not until 1875 the surmise was raised by Newcomb that also the rate of rotation would be subject to irregularities. Only in 1936 was this confirmed by the determination of a seasonal variation of a few milliseconds in the astronomical observations by the BIH.

​
The distance from the sun varies that much or more every year.
​
Why would the Earth being larger or smaller make a difference?
​
Same story re: the moon?
​
Why would more than one moon exclude life? You do know that right now we do have another satellite and we will continue to have it for several thousand more years. don't you?
​
The Earth crust varies greatly in thickness already, yet life exists.
​
See the crustal contour map at this link
​
The ratio of oxygen and nitrogen HAVE varied over the billions of years that life has been around.
​
Check this link as a place to start
​
Ozone does vary already.

One problem with Hugh Ross and his assumptions is that he starts off with an incorrect question. He begins by asking,
​
What are the chances of finding another Earth-like planet capable of sustaining life?
​
which is simply a nonsense question for several reasons.
​
First, what is an earth-like planet? Is it the earth as it was 4+ billion years ago? Is the earth before the moon? Is it the earth today?
​
Second, we are defining life based on a sample size of exactly one. And even with that limitation, we can't even define what exactly is a living organism. Is it you and me? How about the early proto-bacteria? How about viruses? What about extremophiles?
​
As is so often the case, he is approaching the issue from a human-centric point of view. While that is common, and I must admit that personally, I too prefer a human-centric world, it has nothing to do with the question of life.
​
There is nothing that I can see that seems to indicate that either our solar system or the universe in general have been fine-tuned.

As I pointed out a couple posts above, there are several major flaws with such an assertion. First, what we know about life is based on a sample of one. Only when we have been able to examine several (hopefully many life forms) will we have any idea what is required.
​
Until then we really have no idea of what the requirements for life are.

Both. All of the different life on this planet is pretty much the same. There are only insignificant differences between the simplest virus and us. We are all based on one chemistry, one set of rules, one environment, one genetic structure.
​
We have a sample of one.

So the universe is fine tuned for our kind of life?
​
Would it not be equally reasonable to say that our kind of life evolved in a place that was suited for it?
