Christianity seems like a polytheistic religion due to the Holy Trinity but in truth, god is like water it can be steam ice or liquid.
Taken from Religulous.
I'm an agnostic but I'm most inclined to believe the early polytheistic religions are true because they were first. The Christian religion for example is actually all fake and is just a combination of different element of pagan religions. This happened because the Romans sought to unify an empire under a single religion. The myth that Jesus was born on Christmas is only because a previous Roman god, Sol Invictus (a sun god), was celebrated that day.
