Yes. And “a day” can mean nothing to an eternal conscious awareness existing outside of time and space - except as He imagines it, and imagines Himself subject to it. All of Creation is an imaginal act.
The Bible is for man; God doesn’t need it. I think ‘the days’ refers to our material sense that creation is the result of an order of process.

I’ve seen a study - and I’m not sure of all the facts - but it demonstrated that time changes even within several thousand feet of elevation (the world’s two atomic clocks are not exactly the same speed - the difference is minute, but it’s measurable and predictable).
When you extrapolate out the size of the cosmos, the math showed that six days on the other side would be about 16 billion years on this planet. No contradiction at all....not for a God outside of time and space constraints...
