I didn't postulate that the Earth was that old. I just asked if you though it was older or younger than that.
Multiple source of evidence indicate that the Earth formed approximately 4.5 billion years ago.
real life wrote:Francis Crick, Chandra Wickramasinghe, Sir Fred Hoyle are a few who have done the math and agree with that.
Their calculations are more concerned with the span of time between formation (4.5 billion years ago), and the first sign of life (approximately 3.8 billion years ago). None of these people think the Earth is less than several billion years old.

We've been discussing Crick extensively (perhaps that's on another thread... I can't remember). Crick was suggesting Panspermia (not supernatural sources) as a solution to short timespan advance of life. However, as we've seen from the discussions, the limits he places on molecular development are not necessarily valid, and probably way off the mark.
Here is the
other thread.

How about the origin of DNA? How was DNA constructed by a single cell in such a short life span?
You have the order wrong. DNA came before cells, not the other way around. And before DNA there were simpler replicative molecules.
real life wrote:Where did the cell get the information that neither it nor it's predecessors had nor needed?
Again, your assumptions are wrong, so this line of questioning is invalid.
real life wrote:Prior to DNA, what was the mechanism by which life was evolving since there would be no mutations and changes in the (non-existent) DNA?
I'm not sure at what point we start considering something alive, but before DNA there were simpler replicative molecules, and they were succeptible to replication errors (mutations).
real life wrote:If there was no mechanism for evolution prior to DNA, was the cell that first developed DNA an exact replica[/b] of the first original cell?
If so, how did the cellular line copy itself so exactly without DNA?
Again, your assumptions are incorrect, so this line of questioning is flawed.
real life wrote:Seems a little farfetched, if I must be polite about it.
That's because the theory you have developed to explain things is incorrect. The ideas you have expressed above are definitely NOT the standard theories for how the process started.
If you will begin using the standard theories you will find that all of your logical falaciies fall away and all we are left with are questions about the details of the process.
