Spider,
Declaring that there isn't scientific evidence that the earth is much younger and that there is scientific evidence saying that the earth is absolutely billions of years old is nonsense. I invite you to the world of scientific creationism. I read much from
www.answersingenesis.com . May I suggest you go there and "search" for some interesting articles that might enlighten you.
I have been watching some great pieces called "Incredible Creatures That Defy Evolution" by Dr Jobe Martin. He is a dentist that was once an athiest and who was teaching evolution at Baylor Dental College in Dallas. He even was the dentist for one of the presidents. His evolution beliefs were brought into question by a couple of his students. He researched what they had to say and then began researching animals. As a result, he became a creationists and a Christian.
