Thank God brother for replying we appreciate your time. This is the answer in your question;
We can know someone existed because of the things he hath made, for example, if you are a carpenter, the people will know if you are good carpenter in the things you made. The house can't be built by himself, no one believes that the house was alone built by itself. A good carpenter can do good house, but if it's a bad carpenter he can't built a good one.
If you will take a look at your body, we can safely say the person who made you is a smart person because how your digestive system was built, your respiratory, your brain how it works, your breath oxygen and exhale carbon dioxide, then the plants will inhale carbon dioxide and exhale oxygen. The One who made us which I call God is surely the smartest engineer, scientist, evironmentalist, architect for building this wonderful universe. May God bless you
For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:

Hahaha, yeah I understand where you're coming from and I know all of this. BUT, in my book, this all is coincidence. And what we don't know, eg if matter really exist? if we are connected on some higher level? if we formed matter by 'higher' connected energies? even if the big bang is true or not? All of this may be out of our reach to proof the right or wrong and it could be that there is a concept of god, ie something that we can't explain but some 'higher' forces are at play, in my opinion it is for sure no book of stories is providing the truth. Many book of stories are out in the field, and why would one of them contain the truth, while the others are not? Without any proof? Only circumstantial 'proof' based on thought of complexity of life? But how complex is life when eg it turns out all matter in our universe doesn't exists at all and we live in a gigantic hologram? That is something I like to believe, no matter is real, this is just a 'dream' we are in, an anomaly in the homogenous fabric of the universe. But I respect you, thinking otherwise :)
