I believe your explanation answers the easy question, not the hard one. It explains how organisms evolve to be smarter to survive, but doesn't explain why or how the first person perspective exists.

It's actually a different question (sometimes called "the even harder question" or "the vertiginous question"), but if you have ever asked yourself the question of "why am I me and not someone else", the gap in our understanding of consciousness becomes clearer.

To use the same example: If there was a spreadsheet simulating every neuron in my brain, which one would be "I"? The original "I", or the spreadsheet?

Note that this question becomes meaningless if you change "I" to something else, so "both would be me" is not a valid answer. There is only one "I" (since I can't be experiencing the world from two sets of eyes, one organic and one spreadsheet-eyes, simultaneously), so I have to choose one of them.

This does not seem like a particularly difficult question to answer to me, and I suspect it's because I'm not particularly precious about what it means to "be me."

The logical answer is that this spreadsheet, supposing identical mechanical processes - inputs, outputs, stored data - and I would both be convinced that they're "me", and they'd both be correct in that they'd both be something that functions, and therefore thinks, acts, and experiences things identically to me. Two different processes on different hardware running the same code. The concept of "ego" is a result of this code. To me, I'd be "me" and the spreadsheet would be "a copy of me". To the spreadsheet, it would be the exact opposite.

Of course, that predisposes that the software isn't hardware-dependent. But even then, I wouldn't discount the possibility of an emulation layer.

It really isn't hard once you accept that we're not special for being able to think about ourselves.

I think the key point in my theory is that my brain simply hasn't evolved to intuitively conceptualize it. I've asked similar questions before, including what it's like to die and be dead forever, and I can't form an intuitive understanding of it. My brain rejects the premise. But just because I can't imagine it doesn't mean it won't happen. I'm pretty sure I will still be dead for trillions of years into the future.

To your question, the answer is similar. If we remove this limitation of intuition, there doesn't seem to be a real paradox. Both you and a spreadsheet-like copy of you would each claim to be the real you, and from an outside observer's perspective, there is no contradiction.
