I am a Christian so obviously I believe God made it. I’m honestly not sure how to describe His work though. I do not think that the Earth got a mind of it’s own and created itself when something as simple as a house cannot build itself. I think God provided the chemicals and gases needed for this to happen such as Carbon Dioxide, etc. I honestly can’t go into further detail, I can’t describe clearly and scientifically for other people to understand because I go by faith, not science.
