Which is enough to cover most of the coastal cities all over the world.

Well, I don't know exactly how many years.

I don't believe everything I read, no. I do believe researches that are well
based on facts, yes.

Me too.

This is well known. Don't know about you guys, but I used to live on a
mountain which was 700 meters (not feet) high. There were fossils of sea-
creatures all over the place, not only loose ones but some that were on huge
slabs of stone. What our environmental studies teachers (it was a mandatory
subject in my elementary school, all through 6th grade) taught about this was
that whole area used to be covered with sea-water. I don't know if it was due
to the fact that there were no icecaps; but that sounds reasonable.
