Why should i believe in christianity when you can't prove it's real?

dna proves there's a creator, but that doesn't prove christianity or any other religion is true. whose to say your bible wasn't changed completely? why does your god allow millions of people to die of starvation each year? oh, but they didn't take god's true path for them, that's why. your god supposedly knows the past and the future. he knew before hand they wouldn't take the "right" path. oh, but god didn't make us robots, he gave us free will. that's not free will. we couldn't possibly have chose another path because god knew before hand we'd go to hell. i don't know about you, but that sounds pretty evil. i believe there's a creator, of some kind, a higher being more intelligent, but it sure doesn't care about us.
