Religious people that attempt to convert someone?

Why do you attempt to convert people that are not of your religion, and say your religion is the true path? Why do you want these people to be ''saved''? I don't think some of you understand that all humans do not think the same, you by a degree you think so. Every human thinks differently and has different views and opinions from everyone else and also different intellectual levels. It may be easier to convince you of a religion but others it is not, many need proof, many don't. But it is only the scientifically evolved people that will find the actual truth. So I would call atheists a little more...''intelligent'' than most religious people, since it is easy to convince someone as easy as it would be to convince a caveman or a tribal person in Africa. Intelligently thinking is something I don't see in most religious people in which their religion contains a god because they do not intelligently think of the aspects of their own religion since they are convinced with faith and no proof. They do not ask what if he does not exist, or if he is then why doesn't he help us? Why did he do a crappy job at trying to get people to spread religion and convince people? So tell people, do you expect everything that you convince to convert to your religion? I'm not trying to be rude or mean, I've actually typed all this being calm, not being upset over it, I'm just curious as why you think everyone would be able to believe with no problem or go to hell for not believing?
