I prefer to believe in God for the reason that I refuse to believe that everything was created by sheer chance of the right molecules and electrical impulses being in the right place at the right time. Science says that the brain is but a bundle of neurons that send messages to one another, just a few electrons travelling down a piece of string. For me, religious or otherwise, that is a terrible thought. I cannot comprehend the notion that the soul doesn't exist, the soul has to exist. I ask you, have you felt love? Have you felt anger, have you felt happiness, sadness, and every other emotion in between? Emotions cannot be simply messages, they're too powerful and too meaningful to be chance. I don't think I'm expressing myself very well; what I mean to say is, if we live in a world where emotions are just impulses created by the brain's reactions to our sensory organs, then I would not want to live in this world. I believe in God, and I believe that Jesus was a real person, but even if that is not true and they don't exist, it is undeniable that the human soul exists.
Just look at the world, the universe even; how could something so beautiful be created by a random explosion at the beginning of time? For those who ask "What existed before God, who created him?" ask yourselves this; before the big bang, what existed? Nothingness?
I don't ask people to believe in God or try and force my religion on them, but I do ask these questions to make them think. If science is right, and there is no God, no purpose for the universe, then wouldn't that also mean that we as humans have no purpose either? We exist to simply exist, created by chance and born by chance? I refuse to believe that my entire consciousness - who I am, what I'm doing here, my relationships, my family, my emotions, everything - has come into being merely because two random people met and did their thing. I have to have a purpose, I must have been created. That's all the proof I need.
But that's just me. I can understand how people don't believe in religion, that's their point of view, and it's not my place to try and change their mind. But I believe in a God who created us for a true purpose, and that is my opinion, right or wrong.
