'i could justify them after I read reference to the existence of nephilim from ancient times'

I once read in investigate magazine that the museums of the world had around 8,000 nephilim giants sons of gods demi-gods.

they did not display them, as large creatures and / or creatures with large brains, did not fit in with the theory of evolution!

Matthew 24:37

As it was in the days of Noah, so it will be at the coming of the Son of Man.

Luke 17:26
Just as it was in the days of Noah, so also will it be in the days of the Son of Man.
