As to proof for God, here it is: "What may be known about God is clearly evident among them, for God made it clear to them. *For his invisible qualities are clearly seen from the worlds creation onward, because they are perceived by the things made, even his eternal power and Godship, so that they are inexcusable." (Romans 1:19,20)
The above is opinion--
not proof.
The things made testify that they are the results of intelligent design. Intelligence and creativity does not exist apart from mind. And a mind do not exist without a person.
All material items have a design of one type or another, such as we see with snowflakes. Do you honestly believe God patterned each individual snowflake, especially since no two are exactly alike?
That, in fact, is the subject of this thread, why I believe God created life.
I don't have a single problem with you or anyone else believing that God created life, and I think that this very much could be a possibility. I am not an atheist. But I do know there's been an evolutionary process that includes what you call "macro-evolution", so it's really not a matter of speculation at all.
As you might remember, I grew up in a fundamentalist church that taught against evolution, but as i began to study it in high school and then my undergrad and graduate work, it became absolutely clear without any shadow of doubt that I was not being told the truth at that church, so I left it. If a church/synagogue/mosque doesn't deal with reality in this area, which other areas might they also be distorting?
Just remember:
all material things seem to change over time, and genes are material things.
