So if the Mormons believe God was like a man before he was God and that we will evolve into Gods then they are not Christians.

That is your limited understanding and it is not acurate LDS doctrine!

Jesus was always part of the Godhead aka Jehovah in the OT before he was born on earth!

1 Tim. 3
16 And without controversy
great is the mystery of godliness:
God was manifest in the flesh,
justified in the Spirit,
seen of angels,
preached unto the Gentiles,
believed on in the world,
received up into glory.

[Bainbridge]

Limited understanding. No. If one reads the plain text, it is evident that the ideas and claims made by Joseph Smith and the subsequent “Prophets” are far outside the pale of Christian Orthodoxy.
The problem arises when outsiders figure out that there are 2 versions. The inside version and the one used to talk to the “gentiles”. ( It might interest our Jewish friends to know that non- Mormons are sometimes referred to as Gentiles by LDS members!

Admittedly I do have a limited understanding of Mormonism. However, God in man Jesus preexisted from before the creation of the universe and did not "evolve" from his manhood into a God.

If as has been stated here that Mormons believe God was once a man and "evolved" into God that is clearly not Scriptural. If I'm in error about this Mormon belief please let me know what the actual belief is.
