Based on moon rocks, we know that the Earth is about 4.5 billion years old. Life on Earth, therefore, originated or arrived inside that time span.
According to my Jones book on evolution, "The balance of isotopes in carbon entrapped in Greenland rocks three thousand eight hundred million years old resembles that of the modern bacteria that live on methane." (page 208)
Another revelation from Jones is ... "About a thousand genes are shared by every organism, however simple or complicated. Although their common ancestor must have lived more than a billion years ago, their shared structure can still be glimpsed. It shows how the grand plan of life has been modified through the course of evolution." (page 284)
So are you saying you don't know how life started, but it must have evolved?
>>2. Asexual to sexual reproduction?<<
Stochastic progression, as explained in the theory.
What stochastic progression? Most, if not all, stochastic processes increase entropy. Can one demonstrate this this stochastic progression in a controlled experiment?
>>3. Development of “thought”?<<
Clearly a survival need, but it followed the process just like everything else. But there is a lot of debate in the scientific community about that at the detailed level.
There is nothing "clear" about this. How does this "need" arise? In fact, what cause the "need" for life to exist, to form cells, to create specialized cells, to have these cells work in conjunction to make biological machines more complex than any system man has devised?

I am saying it is irrelevant — even now the Big Bang is being challenged and it doesn’t really matter.
eory.

It is not my job to teach you TToE. Educate yourself or not. Your questions pole no holes, but merely reveal your lack of knowledge.
