← Origin Of Life On Earth: Simple Fusion To Jump-start Evolution

These favourable conditions existed very early on in the Hadean Eon (4.4 to 3.8 billion years ago). Earth's "second atmosphere" during this time consisted of nitrogen and carbon dioxide at very high pressures and led to moderately acidic (pH 5.8), initially near boiling (but cooling) oceans.

It makes perfect sense that the environment for long RNA formation would pass through this "sweet spot".

But, of course, something like this happened. Whatever did we think? Godddidit?

People have to stop thinking they "know" the answers before we actually know the answers.

It stops us finding the answers. Self-serving, intellectual luddites!
