Flat Earth, Book of Enoch and the Great Flood of Noahs Time

This thread is not about believing in a flat earth today but was the earth sort of flat before the great flood of Noah's time and now its a globe.

This has been something I have been thinking about for sometime, there were giants in those days, trees grew larger than today, people lived for up to a 1000 years than and dinosaur's roamed the earth than.

Even scientist say dinosaurs could not exist today because of gravity and possible atmosphere, so could the earth have been such a different place than it is today, was it flat before the flood.

The book of Enoch does described a much different world than today and is this why flat earthers believe the world is still flat but refuse to consider it all changed after the flood.

Just maybe flat earth is true before the flood but I do believe its a globe today..

Maybe this is why the book of Enoch was not part of the bible till the last days so man would have a better understanding of the book when knowledge increased, maybe God did want the book of Enoch hidden till the last days.

I do think the earth was so different than it is today and maybe it was flat ?
