So then we can call the Bible "God's Theory" or something like that and it would be more reliable?

Apparently, I am wasting my time because I think that God created the Earth a
long time ago, and evolution progressed as it has. You might want to amend that statement.
What are you going to think and do if we find life in many places besides Earth, like Mars?
I know this wasn't directed at me, but I would think that was frickin' awesome and keep on believing that God didn't make life exclusively on Earth.
If Christianity and Judism were the absolute correct religions, then they would be the first, I'd think.
Which means that the flat-earth theory would be absolutely correct? It doesn't work that way.
contradicts the peacful nature that Christians should follow.
? And this applies to this argument how?
What if I don't want to go to heaven because I think it is too perfect and without free will or hardships?
Be my guest

.
Without hardships, you can't be truly happy.
Without
having experienced hardship. Once you get to heaven, you have still experienced such things on Earth. You can very much be happy.
Look at the heart and morals instead of the denomination.
Thank you.
I'm not sure about that because I see people focusing most of their prays on Mary rather than God/Jesus.
Discussion over. Catholics are Christians. Just because they don't do exactly the same things as you does not make them not Christians. They may very well be mistaken, but that isn't the point.
Also, quite a lot of people detest any religion by looking at histories of the religions.
The same thing applies to many, many countries. Besides, past performance is no indication of future performance

.
I suppose I would class myself as agnostic and believe myself to be a good person, does that get me into heaven?
No.
