The only problem I have with the belief of creationism that the earth is only 6,000 years old is that (prove me if I'm wrong):
you haven't studied
geology,
climatology
paleontology
archaeology
biology
chemistry
Botany
Astronomy
anthropology
and many more Ideologies and conducted studies concerning life, earth characteristics, and/or atmospheric characteristics to be able to make a legit argument that the earth is only 6,000 Years Old
and Taking classes doesn't count.
The only reason why you believe that (sorry no disrespect) is because some priest who didn't study this either forced you to believe that people who actually study these things for a living are wrong.
The 6,000 year old earth is an irrational, illogical argument, with no way of proving that your theory is right, compared to the substantial amount of scientific evidence against it.
