You keep getting this wrong. Yours is a belief system just like ours. Your belief system says God does not exist. But it is no more difficult for God to exist than not. Therefore, you are obligated to prove his non-existence.
You mistakenly think the burden of proof is ours alone. You are obligated to prove his non-existence. Until you do that, we can claim life arose via God’s command all day long and you must accept it as a viable option.
