I don't really understand what you mean tuppence.
The earliest bar on Helix graph is about 4,5 million years ago. That places it in the Pliocene if I am correct.
According to the combined timeline on your page the entire Era in which the Pliocene was (Cenozoic Era) was only 660 orbital years long.
That doesn't even give the bar 20 orbital years but much less. It is getting more and more ridiculous.
We never found evidence for human life in the Archaeozoic Era. Where did you get that from?
So we are still back at Helix original point: "You are not just selecting bits of information that suit your 'theory' and ignoring the rest, are you?"
You did not manage to stop my sarcasm (yet?)
