Atheists, what is your explanation for what happened before the big bang / beginning of time, etc?

Just like you guys, I reject religion. However, I do not consider myself atheist. Atheists deny the existence of a god while my beliefs consider that God was the ultimate cause of the universe. However, God does not directly interfere with our lives, or anything else. It is our job as living beings to use science and knowledge to figure out the mysteries of the universe we live in. However, there are some things that cannot be explained by science, such as the beginning and end of time. The big bang was probably the predecessor of the universe, but what created that? If there is no way to figure out what came before that, I use that as the concept of God. It's like God started time. The concept of time can be rather complex, and having the universe come out of nowhere does not make sense. With that, a being so divine and powerful must be the ultimate cause of the universe. God is an entity that you cannot feel with your senses, but can only be comprehended in your mind in a unique way. Because the only thing God did was create the beginning of time, I feel no need to worship God in any ways or make any special amendments to my life.

TL:DR, To me, God is the divine being that pressed the start button on time but that's all God did. No need to become religious nutjobs.

Edit* Thanks for the discussions guys, I'm not here trying to rile anything up, but just to hear your views and express mine. Unfortunately r/atheism is place where people prefer to post rage comics than discuss these philosophical things. I'll know better next time, thanks!
