So based on your logic where did that designer come from?
Isa 57:15 For thus says the One who is high and lifted up, who inhabits eternity, whose name is Holy: I dwell in the high and holy place, and also with him who is of a contrite and lowly spirit, to revive the spirit of the lowly, and to revive the heart of the contrite.
Inhabiting eternity indicates being outside our time domain, outside of our past, present and future. Similar to a programer of a computer universe who is outside the program and dictates the physics, time flow and organization of what is real within the program.
The “Designer” always was and always will be.
Otherwise there would be no Prime Mover.
Secular Evolution is constrained by time and space.
God is not.
Logically, if something cannot come from nothing, and something exists now, then something must always have existed. There must be at least one thing that is eternal in order for anything else to exist, if the axiom is true.
