We naively assume the past to be in a state of less entropy and the
future to be in a state of more entropy, just because we have memories
in our brains from when the universe was in a state of less entropy.

An equally valid interpretation of reality might be that the future is
evolving towards the past. Who is to say if a photon is absorbed by a
molecule into the future, or if the same photon was emitted by the
same molecule into the past.

If my memory-structures came from when the universe was in a state of
more entropy I would certainly believe the universe to be evolving
towards a state of less entropy. Then I would believe yesterday to be
in my future, and tomorrow to be in my past.

No, we assume the future will look like the past. We see increasing
entropy as we move forward in time. It is clearly displayed in the
Universe around us.

that the future is evolving towards the past.

It may or may not be valid, but it is entirely moot. If you wish to
"reverse sign", we can certainly do that.

Who is to say if a photon is absorbed by a
molecule into the future, or if the same photon was
emitted by the same molecule into the past.

Convention.

Entirely useless, incorrect, and now wandering off into the woods from
where you started. Do you want to talk about black holes, or *be*
one?
