Sample Comments
Did you mean hundreds or thounsands of millions of years?
Maybe a after a couple thousand decades :-)
More like 1000 years, but still: much longer than is useful to anybody alive now.
Billions of years is a gross understatement.
Thousands of years, or millions?
Just a few decades out of... millenia.
What timescale are you thinking on, 75 years or 15000 years?
Multiple millions by thousands of years. Probably yes.
It's been a few hundred thousand years, I believe.
What's a few billion years anyway
