how anyone in this life or any other life could think of GOD having blood
As a theological concept it actually has much appeal. We are in God's image right? Judaism's founding texts certainly had no problem with their God having a body. He walks around and eats and interacts like anyone else. Many Rabbis throughout the centuries asserted he did have a physical body. While others disagreed it was due to the increasing sophistication of their theology not by textural rebuttal. It makes God accessible and relatable like the Jesus figure does centuries later.

Interestingly millions of Christians today embrace the idea of God having a body...they are called Mormons:
Doct&Cov 130 22 The aFather has a bbody of flesh and bones as tangible as man’s; the Son also; but the Holy Ghost has not a body of flesh and bones, but is a personage of cSpirit. Were it not so, the Holy Ghost could not ddwell in us.
