Is there a wrong religion to worship?

I’m not much of a religious person, however my mothers side of the family is…strong christian faith. I don’t do a lot of research on religion. One thing I hear often from Christians, is that Buddha, and Ala are false idols, and for worshiping false idols you would go to hell for it. However a friend of mine who is Buddhist told me that there have been many buddhas and that even Jesus Christ could have been a buddha (he said one who shares enlightenment is considered a buddha?) Not sure. It seems to me that maybe my mother’s side of the family is just too narrow minded?

Maybe some input from Christians, and also some Buddhists. I just find it hard to believe that someone could really go to hell for worshiping a religion that he/she was brought up to worship and had little say in the matter.
