The Origin Of Life Made Easy
This is a great video going through, Step by step, Explaining how simple elements can over time combine to create more complex chemicals, Which in turn combined to produce self replicating molecules and eventually primitive cells.
He keeps going on about this experiment that proved amino acids could form -- he's not talking about the Miller-Urey experiment is he? That thing was discredited years ago -- wrong atmosphere, lots of sludge that would prevent further reaction, and the system itself would destroy what it created if the molecules weren't quickly removed. You need to do better than that.
The Miller Urey experiment was long before 1961 wasn't it?
I haven't actually seen any credible sources that discredit the miller Urey experiment though. Even if the conditions in their experiment weren't exactly the conditions on earth (how could they be, it was done in a lab) they still proved that the compounds and molecules need to create DNA were able to form themselves.
FYI, the 'Miller-Urey' experiment has been repeated several times with an atmosphere that does resemble the likely early primordial atmosphere (resembling volcanic outgassing) and the results were the same -- about 13 of the 20 usual amino acids were produced.
That's in one week in a lab flask -- imagine a billion years on the early planet.
