That's because it isn't true. Torah says that Hashem is one and He is not a man. Man-gods are of pagan origin.
Dead Idols and the Living God
1 Bel bows down, Nebo stoops; Their idols were on the beasts and on the cattle. Your carriages were heavily loaded, A burden to the weary beast.
2 They stoop, they bow down together; They could not deliver the burden, But have themselves gone into captivity.
3 “ Listen to Me, O house of Jacob, And all the remnant of the house of Israel, Who have been upheld by Me from birth, Who have been carried from the womb:
4 Even to your old age, I am He, And even to gray hairs I will carry you! I have made, and I will bear; Even I will carry, and will deliver you.
5 “ To whom will you liken Me, and make Me equal And compare Me, that we should be alike?
6 They lavish gold out of the bag, And weigh silver on the scales; They hire a goldsmith, and he makes it a god; They prostrate themselves, yes, they worship.
7 They bear it on the shoulder, they carry it And set it in its place, and it stands; From its place it shall not move. Though one cries out to it, yet it cannot answer Nor save him out of his trouble.
8 “ Remember this, and show yourselves men; Recall to mind, O you transgressors.
9 Remember the former things of old, For I am God, and there is no other; I am God, and there is none like Me,
10 Declaring the end from the beginning, And from ancient times things that are not yet done, Saying, ‘My counsel shall stand, And I will do all My pleasure,’

Jacob’s Return to Bethel
1 Then God said to Jacob, “Arise, go up to Bethel and dwell there; and make an altar there to God, who appeared to you when you fled from the face of Esau your brother.”
2 And Jacob said to his household and to all who were with him, “Put away the foreign gods that are among you, purify yourselves, and change your garments. 3 Then let us arise and go up to Bethel; and I will make an altar there to God, who answered me in the day of my distress and has been with me in the way which I have gone.” 4 So they gave Jacob all the foreign gods which were in their hands, and the earrings which were in their ears; and Jacob hid them under the terebinth tree which was by Shechem.

Jacob returned to the Land and they buried their idols under the tree.
So how would a Jew convert to paganism?
Reverse the process, go to the (Christmas)tree and pick up their idols.
Oy gevalt cubed!!!
