What are the problems with believing in millions of years?

“Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned.”  Romans 5:12.

Death and suffering is a result of sin.  In the fossil record we find bones with diseases and cancer.  If the fossil record shows millions of years of Earth history before the creation and fall of man, then what caused those animals in the fossil record to die and have diseases?  The fossil record is a result of God’s judgment of sin.  These things logically could not have happened until after Adam’s sin.  This is one of the major problems with Theistic Evolution and Progressive Creationism in that these two alternative views allow for suffering and death before Adam’s sin.  This is opposite to what the Bible tells us about sin, suffering, and death.   If Adam’s sin did not bring death and curse onto the Earth, then what did bring it?
