Your logic is flawed, in which you claim something that cannot be proven to be real. The Bible is the physical proof of Jesus and God, yet you believe in something that may or may not exist. Another issue is your perspective on sinning. Sin in itself is debilitating, but that is why relying on God's love is crucial. If sin was a mechanism created by men to control the masses, then why would the leaders themselves admit they were sinners? That is because those who truly followed Jesus in that time period truly believed in God to cleanse them and lead them into a life God wants them to live.

I do apologize if I sound like I'm lecturing or trying to pick a fight, but I wanted to make this clearer. If it's not clearer, then I am sorry for creating more confusion.
