Judaism The most powerful reason on why I reject Jesus as messiah

[serviteur]

Jesus was not of the line of David, and therefore was not the messiah. I am going to use the Christian Bible and genetics to prove it.

Jesus’ adopted father Joseph never impregnated Mary, since Mary was somehow impregnated by G-d (Matthew 1:18). Therefore Joseph’s Israelite y-chromosome (a feature that can only be passed down from a human father to a human son through sperm) could have never been passed down to Jesus. Because of this, Jesus was not an Israelite, nor did he carry the root of Jesse. Instead, Jesus was just a demigod. Therefore, Jesus would have supposedly carried the y-chromosome of G-d, suggesting that G-d is a man… and G-d is not a man (Numbers 23:19). G-d does not have a y-chromsome because G-d is spirit.

[b]"1[/b]The LORD appeared again to Abraham near the oak grove belonging to Mamre. One day Abraham was sitting at the entrance to his tent during the hottest part of the day. [b]2[/b]He looked up and noticed three men standing nearby. When he saw them, he ran to meet them and welcomed them, bowing low to the ground.
[b]6[/b]So Abraham ran back to the tent and said to Sarah, “Hurry! Get three large measuresa of your best flour, knead it into dough, and bake some bread.” [b]7[/b]Then Abraham ran out to the herd and chose a tender calf and gave it to his servant, who quickly prepared it. [b]8[/b]When the food was ready, Abraham took some yogurt and milk and the roasted meat, and he served it to the men. As they ate, Abraham waited on them in the shade of the trees.Then the LORD said to Abraham, “Why did Sarah laugh? Why did she say, ‘Can an old woman like me have a baby?’ [b]14 [/b]Is anything too hard for the LORD? I will return about this time next year, and Sarah will have a son.”
" Genesis 18

Why does abraham referred to GOD and the the two angels as men?  And how can the LORD eat the yogurt and roasted meat if He is only spirit? Can a spirit GOD eat ?why is GOD referred as THE LORD(aka GOD) and man at the same time? Why does one of the men refer himself as THE LORD(aka GOD)?
