Since Jesus was Jewish...
 

What did Jews believe BEFORE Jesus??? Or was Jesus the first Jew? I don't know I'm very uneducated as of yet.

Read the bible and you'll know.
They had men of god before jesus.
God speak to some of them.
Its not like god worshipping came around when jesus did.

Jews were waiting for the messiah.....
Jesus was the messiah supposedly
The Jews that didnt believe that stayed Jewish
And the ones that believed it
Became a different sect of Judaism
Now known as Christianity

Mhm.
I don't know.
He was Jewish. Thats it.

what did jews believe before christianity...judaism perhaps?

I still don't quite get it...

Jews wanted their messia to come.
Then when he supposedly did, they didn't believe him so they stayed Jewish???

Some did, some didn't.

Yes, some jews dont believe he was the messiah and that he was just a prophet and that he never died. Someone that looked like him was hung on the cross instead.

^Exactly they thought Jesus was a blasphemous false-prophet so they had him killed.

Looked like him?
