In prehistory, religióon was a manner to find an explanation to all things theat man did not understand.

Unfortunately at present, religion has become a problem in the moment that one person wishes to impose his beliefs ton others.

I don't think it's necessary to have 'in the moment' in the middle of the sentence, since you started it with 'at present'. You said the same thing twice.

All people are free to beliefve in all they wishing, certainly, but without imposing anything ton the rest.

We all must to have to respect the beliefs or not n-beliefs of other people, and to live all in peace.
