Yes I agree with plymirize. If all of these things were disproven than whomever it was that challenged the US government on the topic of teaching creationism in school would have actually had something to say in their defense.

I think that information is posted on some Christian website. So people will read it, it reinforces their believes. and they feel no need to verify the information.

It follows a nice little psychological "formula:

A person has a belief
A person is confronted with a piece of information

If this information is consistent with the belief then, information is accepted at truth. Little thought is given to it

If the information is inconsistent with the belief then the person must choose.
1) Modify the belief so it accommodates the new information.
2) Disregard the new information

(the second option, if it’s inconsistent, is a highly critical approach.)
People are very critical and place less faith in information that contradicts their belief. And they aren’t very critical at all about information that confirms there belief.
This is called confirmation Bias

Everyone is subject to this. I believe this is one main factor in why people can believe so strongly in something like creationism and not believe in evolution.

Someone makes a website writes a bunch of lies on it that disprove evolution. And oh, you stumble onto it and wow your beliefs are reinforced because of lies.

A few days later you forget what you read but the beliefs prevail, stronger now.
