The number "4.5 billion years" (or in Sagan's case, "4.5 BuhBuhBuhBillion years") is thrown out as if it were something approaching eternity and therefore almost anything is possible. But that isn't science, it's myth-making just as surely as someone making up religious stories. Where is the math? If the math doesn't work, the mechanism doesn't work. If you don't have the math, you don't have the argument.
No it isn't.
and therefore almost anything is possible.
No one makes that argument, but thanks so much for the straw man fallacy.
But that isn't science,
...which is why science doesn't do that, contrary to your dishonest accusation...
it's myth-making just as surely as someone making up religious stories.
Ooh, an admission?
Where is the math?
See my post #158.
That'll get you started. If the math doesn't work, the mechanism doesn't work.
The math does work.
If you don't have the math, you don't have the argument.
We have the math and the argument.
If you disagree, then you're cordially invited to respond to the same challenge I made to the other nitwits in post#158.
