First, evolution wasn’t created by man, evolution shaped man, we just gave it a name. Second, evolution and atheism aren’t mutually exclusive. I believe in evolution because it has been scientifically proven and observed. It is a fact, not a maybe. I am an atheist because there is no proof of any kind of god. Also, there are Christians who accept evolution as fact and when I was a Christian I was one of them.
I went to a Christian school and was a Christian when I was younger. In my biology classes at that Christian school evolution was part of the curriculum and we were also taught that the earth was billions of years old. I know, blaspheme! The belief wasn’t that it was 6,000 years old, the six days it took God to create the world was actually billions of years because billions of years to us is like a day to Him. Of course, I now know that to be ridiculous and I will come back to this in a bit.
I don’t believe nothing created everything. There was something before the Big Bang. Scientists have theories and I am certain that one day we will know how the universe came to be. It will probably not be in our lifetime, but I hope it is. Saying nothing created everything is religious rhetoric, it is not a widely held belief in the scientific community.
As for life on earth, we don’t know how it started. There are theories and it will take time and tests to figure that out. Some think that life was brought here from asteroids and comets or that organic molecules formed in the protoplanetary disk of dust before the earth formed or that life was created shortly after the universe began and life has always been floating around out there or perhaps it is started in a way no one has ever thought of. We may never know the origin of life, but we can figure out how it evolved on our planet and, if we ever visit other planets with life, we will be able to figure out how it evolved on that planet.
You spoke of atrocities, but have you ever sat down and read the Bible? If the Bible is to be believed, then God is one of the worst villains in the history of man. He not only condoned rape, genocide and slavery, He ordered it. We, as a society, find those things to be immoral. So, why someone who is more moral than God would follow that being is beyond me. Also, He does not know what love is. Love is not, love me or burn for eternity, it is unconditional. An ultimatum can never be love.
Why I find the Bible to be ridiculous is because it is a badly put together story written by authors who pulled stories from other religions, repeated stories with different characters and preached fear. Maybe when the men wrote the Bible they needed to instill fear into the men around them to create a civilized society or maybe they just wanted to create a history like Tolkien wanted to with Lord of the Rings, which are much better books by the way. We will never know what their intentions were because they did not write those down.
As for the Gospels, there are holes and contradictions between the books. Apologists like to mash them together, but read separately they each tell slightly different stories. Plus, there is no other evidence of Jesus’ existence. The Romans were wonderful keepers of history, why no mentions of Jesus during the time he supposedly lived?
Again, I don’t believe in gods because there is no evidence to support the existence of one, but if a god did create us or this universe than it is not the God of the Bible. It obviously doesn’t care or isn’t powerful enough to interfere or help us. The Biblical God is just as made up as Zeus or Odin or pick any other god you don’t believe in.
