I have read and seend documentaries in a number of places that say the Earth was nearly all covered with ice 300M years ago. Pretty scarey stuff—hopefully it will never happen again while the human race is around.
'Snowball Earth': Glaciers, ice packs once met at Equator
****************************EXCERPT Intro************************
American boffins say they have discovered evidence that almost the entire world was covered in sea ice and glaciers at certain points in the remote past, during so-called "snowball Earth" periods where the polar ice sheets met at the Equator.
It were grim in the old days.

Well, the Second Coming is bound to happen before that. I.e., it seems disproportionate that from the time of Abraham to Christ would be 3000 years, and from the First Coming to the Second Coming would be millions.
The poles were in a different place 300 million years ago, the theory is that Earth hadn’t yet been hit by the astral body that knocked it slantwise on its axis and started that wobble.
