I do not claim to be right but how would you explain this...
26 Then God said, “Let us make man in our image, in our likeness..”
However in the very next verse...
27 So God created man in his own image, in the image of God he created him; male and female he created them.
That’s a darn good point! I’d never noticed that the next verse is singular. Only the trinity, or something like the trinity, seems to make sense putting the two verses together, Genesis 1:26 - 1:27, since one is plural and one is singular.
Let US create....
sure indicates at least a binary...
