"Are you trying to tell use that the son is also the supreme being ,God almighty?"
Yes
"Are you saying God almighty ,who has no beggining of days ,the self existent one,is both the father and the son?"
Yes
"Is this what you are saying is that simple?"
Yes, simple but a mystery. You do understand that we as mere humans do not fully understand God. What we are told in simple terms in the Scriptures though show that God the Father, God the Son and God the Holy Spirit are three Persons of the One True God. It's a mystery.
