Liz,
No, it is clear that your here is not the same as mine because you
are not here. However it is quite clear that you absolutely must be
doing something in the exact same present moment that I write this
sentence. That is the present moment that we share.
No, that's not clear at all. Since you and Liz are not in the same
place and the speed of light is the same in all inertial frames,
there exist a whole range of Liz's moments which may correspond to
your moment depending on which moving frame is arbitrarily chosen to
determine simultaneity.
Yes. Presentism does not make sense with special relativity. "present"
is an indexical. No need and in fact no means, to reify the "present".
Do you somehow imagine that there is some gap in your time line
that takes you out of existence as I write this sentence? If there
isn't then you must agree we do share a common present moment...
But it is not uniquely defined.
A long time ago, in my childhood, I saw a movie with a friend. My
friend found the movie boring, and he felt like if it never ends: time
was going slowly, for him. But I loved that movie, and time was going
very quickly for me. We discussed that after, and I was troubled. Was
we still at the same moment?
Well, with computationalism, that question just does not make any sense.

It's self-evident that everyone has a present moment, which they

current position, which everyone will tell you is "here".
Hence everyone is at the same time, and in the same place.
