I dismiss the idea we can't know until we know all. You choose to believe natural & choose to believe we will know more one day to explain how what you already decided to be true is true, Sounds like faith based circular reasoning to me & just as religious as any religion.
How do I know you're real? You can come up with a lot of excuses to ignore & dismiss anything. Your excuses are "it's natural" & "we don't know everything so it could be anything." Not logical & it seems in your view God must be the last option & avoided in favor of anything else.
Yes, there is a God who is both the source & cause.
You can't create or cause the material that caused the Big Bang for example. Were looking into the past to the very beginning & I do not believe nothing can create or cause anything so logically there must be a ever existing source with no cause or beginning that started existence. & if to start existence that means this source was before Space, Time, & Matter.
Undetectable? Yeah, maybe but that would mean God would have to want to make contact with his creation doesn't it.
Where is God? I direct you to the term "omnipresent" God is everywhere. Bigger than the universe but chooses to live in the hearts of those who accept him.
Ha, Jesus is believe to be the God of the Bible by many so he is very relevant. Because Jesus brings eternal life to all who accept him. All the words spoken by Jesus are important to me.
You think I wrote this meme? That's a quote. Yes there are scientist who believe in God. Science was started by those who had the idea they were thinking God's thoughts after him, Johann Kepler
