No. More like existing together before time and space existed.
It's all in the Nicene Creed.

So Jesus and God are the same entity existing before time and space existed? That doesn’t add up. What does space and time have to do with this?
When Jesus ask for God’s help, is he talking to himself or another entity?
I think the usual formulation of the Trinity is three coeternal persons (hypostases) sharing one divine nature (homoousion).
A good thing to keep in mind is that the Trinity is a mystery that's not fully revealed to us. What are the three's interactions, for example, at the time of Jesus' baptism on the Jordan river? We have the Father talking to the Son and the Holy Spirit descending, but why did they do it like that?
I dunno it doesn’t make sense to me…
