Creationism is based on more than just the bible.
Saying what you said is like saying the evolution theory is based upon pretty pictures painted in science text books.
The bible is important yes there is no arguing that however science does easily point the way for a 6 day creation and a 6000 year time line for the earth (if you are open minded enough to subjectively put the evidence together). To proof is there. To say otherwise would simply be ignorant.
The going back a few posts, I will also say that no evolutionist in their right mind will call evolution science.
If you are open minded enough to truly view the creationism point of view from scientific data, feel free to view or download the free videos found on this site:
http://evolution.no-ip.net. I suggest downloading one of the files and fast forwarding past the stuff in the first 20 min of the file (that’s the introduction and Christian mumbo jumbo). After that point the speaker begins to cut the chase and display overwhelming facts that destroy the evolution theory in many ways and pretty much proves creationism as a viable history for the earth. The speaker uses pure science (like laws in physics) to show the approximate age of the earth and shares overwhelming scientific data that damages the evolution theory.
I saw and downloaded all 20 hours of online videos and it drastically affected my mindset toward evolution (in a positive way).
