For two reasons:
- It doesn't contradict the Scriptures.
- I give scientists the benefit of a doubt.
If the Bible says that we have only been here for 6100 years, and science says this earth is 4.57 billion years old, I see no contradiction between science and the Scriptures; so long as I make the distinction between
existential years and
physical years.
The mistake "scientists" are making, in my opinion, is that they look at an object, and see that it is 4.57 billion years old, and assume it has 4.57 billion years of
history in it.
Zircon, I believe, is the oldest known substance on the earth.
If Zircon has gone around the sun with the earth 4.57 billion times, why isn't everything else 4.57 billion years old?
I conclude therefore, that "scientists" are confusing age with history, but God didn't.
