I believe it is stated as:
“God himself was once as we are now, and is an exalted man...and you have got to learn to be gods yourself.”
Journal of discourses 6:3-4 (Joseph Smith)

Now this doesn't sound too good. So the church is finessing it, and revising and developing and denying it and the verbal gymnastics required are absurd. But if you do some basic research you cannot avoid the fact that this is a foundational belief of the LDS church. And so no, they are not Christian.

Thank you for the notation. I know you won't find anything alluding to this in Scripture.

Gen. 1:1 In the beginning God created the heavens and the earth.

God preexisted everything. God could not be the product of evolution. God existed before anything began.
