I think it would have more significance, imagine there was a single immortal entity that looks exactly like one of your body parts. I guarantee you people are chopping off each other's hands and offering them to the "hand god". And don't even get me started on feminism, is it a male hand, is it a female hand? What does it mean?

Philosophy, science and even art would all be vastly different. Imagine you're Martin Heidegger and you try to reason that mortality makes an authentic and meaningful life possible. Yeah sure Marty, then why the fuck does this giant hand squish people? This giant hand is immortal, and it's giving all of our lives meaning. Do you not think the fucking hand knows that? Do you know why the hand is doing what it does? Do you think we're somehow better than the hand because we die?

Or maybe you're Frederick Nietzsche. And you are wondering about eternal recurrence. Would someone willingly live the exact life forever? I don't know dumb ass, have you considered asking the big giant floating hand?

These are just a few examples but you are vastly underestimating the significance of the giant floating hand.

I think the main thing about it would be the destruction it caused on its journey. Ploughing through cities and into buildings. Still an extraordinarily rare occurrence but with a lot more evidence for its presence.

And God forbid it chooses someone who spends time underground.
