I now feel it doesn't matter much, although there have been many archeological finds that disproved previously held evolutionary theories about layers of earth - many of them suppressed by the scientific community-at-large in much the same way Covid dissent was suppressed recently.
I have GOT to challenge that statement. Go to the Grand Canyon (I have done so) and look at the sedimentation deposit layers to see how many of them there are and start adding up the years for each. I also have seen the ludicrous arguments that ignorant people have made using religion to attempt to negate the laws of physics regarding evaporation and sedimentation. When a religious apologist tries to negate raw, testable physics, the only respect earned that way is that the apologist has a career in self-deprecating comedy.
That's a decent point about the age of the world. (although I was raised to think along the lines of 10,000).
If you follow Bishop Ussher, you get about 6,400 years (or is it 6,600 by now?) I forget, but it is in that range. If you ARE using 10,000, you are looking at the age of non-Christian civilizations such as are found in S.E. Asia. That isn't a Christian teaching.
Then comes the response: "Oh, but it could have.....over billions and billions of years"
(I trimmed that to keep this next part short.)
In one cubic centimeter of water, which is 1 milliliter, you have approximately 3.34 x 10^22 molecules of water. Let's say that you have approximately a 0.1% (one part per thousand) concentration of the other molecules required to start the formation of life. That means you have 3.34 x 10^19 molecules of your reactant. At any temperature supporting liquid water (273 to 373 Celsius) you have literally billions of molecular collisions per second. At 20 degr. Centigrade (293 C), water molecules travel at about 590 m/sec. In a milliliter, you have a cubic centimeter of space for movement so you get 59000 cm/sec. I will make that the rate of collisions (although that is probably low).
We have 59,000 collisions per second * 3.34 * 10^22 molecules colliding * 0.001 (allowing for concentration = 2200 x 10^22 collisions per second. I'm going to be generous here and say that only another 0.1% of the collisions are favorable. Which means 2.2 x 10 ^22 potentially interacting collisions. PER SECOND. Now, a year is 60 sec/min *60 min/hour * 24 hours/day * 365.2422 days/year. That is 31,556,926 seconds (rounded to the nearest second). So, in one year you have 31,556,826 * 2.2 x 10^22 potentially interacting collisions = 69,425,237.376 x 10^22 collisions. Normalizing that format, you get 6.94 x 10^29 collisions. IN ONE MILLITER of impure water in ONE YEAR. Now, let's say that we have about 1 billion years. That brings in another 10^9 to the mix, 6.94 x 10^38 collisions.
OK, let's do this for more than one milliliter. According to NOAA, the Earth's oceans contain 321,003,271 cubic miles of water. OK, that is about 4.16818183x10^12 liters per cubic mile = 1,338,000,011.18286406 x 10^12 liters or 1.338 x 10^21 liters or 1.338 x 10^24 ml. So that means that the earth's oceans would have had the potential for 1.338 x 10^24 ml * 6.96 x 10^38 collisions over a billion years, which is 9.312 * 10^62 potential collisions.
Now, let's be EXTRA generous and say that it took a quadrillion collisions to generate that first viable chemical that started the cascade to where we are now. One quadrillion (USA measure) is 10^15. SO.... that means Earth had 9.312 x 10^47 chances to get it right. You want to say that only the top liter of water would have enough light? Trickier, but let's say that is only the top one millionth of the oceans. Which is 10^6. Meaning we still had 9.312 x 10^41 chances to get it right.
OK, I was winging it a bit - but that number is 931,200,000,000,000,000,000,000,000,000,000,000,000,000 chances for life to start spontaneously in the primordial soup.
This is the problem with people who talk about the probability or improbability of some event. They don't comprehend the magnitude of probability and therefore should never argue fine points about it.
