There are many definitions of "even," one of which the OP is appealing to in order to try and substantiate his belief that Jesus is the Father who became the Son and the Holy Spirit, who both then entered eternity, creating the Trinity. It's a Oneness theology attempt to create a Trinity, for some reason.I fail to see the difference between the use of "and" or "even" in the OP.
To an English speaker they read the same either way.
Maybe there is a difference in American.
Could anyone point out the difference?

Note under its use as an adverb: "d --> used as an intensive to emphasize the identity or character of something"
In all fairness to you, it is hardly ever used this way.
