Religion & Faith

I apologize for my excessive questions/comments but as of lately because I have been getting so many different thoughts about the moment of death and what follows, according to the orthodox church in general, I have began to doubt the existence of God because of these contradictories/uncertainty. I have asked two Coptic priests, and they mentioned eternal life, but were very uncertain about the intermediate state. I have recently begun to view miracles as coincidences and that these occurrences do not necessarily correlate to God. I feel as if we as humans create religion as a source of comfort. In general, just the differences among the churches in Christianity makes me doubtful. Forgive me for disturbing you.
