In the beginning, God created. How long ago, it doesn’t specify.
And the earth became without form and void. How much later, it doesn’t specify. You can ask Peter, John & Jude for the details. HINT: Satan was involved.
And the Spirit of God moved upon the face of the waters...THEN the Seven Days started.
The earth is old, and so is the universe.

Sincere question for you. Before the curse, there was no death, and I’d conclude also no physical decay of any kind. The creation was perfect. So, how do you see behind that event? I’d posit that there was no decay of any kind before sin and the consequent curse on all creation. Creation went from perfection without decay, to something ridden with entropy, decay and death.
