Not scripture per sa young Earth creationist tend to feel that based on genealogies and other dates in the bible the Earth is around 6-10 thousand years old , people actually believe this shit despite all the evidence to the contrary
Geneologies don't indicate the age of the Earth/universe.....although I def. understand the mistake as I used to subscribe to that.
The bible does not indicate an age for the earth/universe...but imo, it does indicate and age for life...which yes, is young.
And as for "evidence to the contrary," there are flaws in carbon dating and the geological column, etc.
I think I've seen 240 say that diff. people have faith in what they think is right. I agree w/him. It's faith on both sides.
