Jacob did know he was wrestling with God.
Gen 32:30 And Jacob called the name of the place Peniel: for I have seen God face to face, and my life is preserved.
Jacob knew he was wrestling God, he said he had seen God "face to face" and yet his life was preserved. He seems to be slightly surprised that he survived this event.
And Jacob absolutely demanded that God bless him before he would let go.
This is not a difficult passage, a child could easily follow this story. I read this story as a child and had no trouble understanding it.
And if I insulted you I am sorry. You do not like the idea that Jacob prevailed over God in this wrestling match, but that is exactly what this passage says. I don't know what to tell you, take it up with God, I didn't write the scriptures.
I tried.........blessings!
