For some, the belief in a Young Earth seems to be based on a kind of intuition or faith in what they believe an omnipotent God should do. It reasons that if God is all powerful, then certainly He would not have taken millions of years to make the earth.
Jesus is the only way because the Bible says it to be true. Why? Because only He can bridge the gap between God and man; there's no other way.
All views can't be true because all views are opposite; this is the logical aspect. For example, Islam says we are good in nature; Christianity says we are born in sin. Islam says God is a man; Christianity says He is more than a man, He is God. All truths can't be the same.
