Because it's what we need

Yesterday in religion- class we talked about an explanation for the existence of God. I read some really interesting stuff.
Today my friend and I talked about it, and what we think about God. I’m not the most religious person on earth, I don’t believe everything the bible says. But for what I do believe, is that some of those explanations are kind of logical. For example they said, that every resault has a cause. The resault of being pregnant is a baby. The resault of staying up late in the evening is being tired in the morning.
So if the earth or us people are the resault, what is the cause? Thomas von Aquin says, that the only cause can be God. Even though I don’t really believe in God, this argument kind off got me thinking. What is the cause, for me sitting here, writing this? What is the cause of 6 billion people walking this earth?

Is God the cause?
