Plato..

my mission here is to prove god exists..

my first approach is not to use religion (this might be deism?)

However, I believe in the religion of Islam.

Later on, I will take another approach where I plan to introduce Judaism, Christianity & Islam to prove existence of god.

Tallg,
This is why I try not to talk about religion to non muslims because some of them feel uncomfortable. However, I do talk about religion when I see an oppurtunity and acceptability to discuss such issues. I think also that muslims should know enough and have nice approach to be able to convince and so on so beforehand and preparations must be performed.

PM,
you are really contributing to my knowledge here. I do share this idea in a slightly different way: sometimes I ask myself, if religion is not right, why would it ask humans to help the poor and donate resources, and not cheat, and not lie. What benefit would relgion get by asking us to do so? Those ideas help me stay faithful. I shall refer to those later on the prove attempt.
