Welcome aboard.
You have a major choice to make now:
1) Do not look into any reasoning or evidence behind the age of the earth if a young earth is necessary to maintaining your faith.
Many of the Christians here will, as Phat as done, point out that you can be a solid Christian without having to take the earth as being 6,000 years old but that is for you to decide.
2) Look into the most current threads discussing the age of the earth in the Dates and Dating forum.
Age Correlations and an Old Earth: Version 1 No 3 (formerly Part III) is a concentrated look at why the idea that the earth is young is untenable. Make sure you understand what "correlations" are about before you post there. No creationist has managed to handle the contents of that thread yet.
If you dig into that you will be faced with these choices:
1) Ignore the evidence and carry on. Some can do that; others find it intellectually dishonest and disturbing.
2) Adjust you're views to that of the majority of Christians as to the age of the earth and what the Bible is actually trying to teach you.
3) Decide that you God is named Loki the trickster God of the Norse.
Good luck. You seem to be someone who is both open and honest. We welcome that here no matter what your views.
