No, we are on the surface. The surface is "now". The center is t=0
(actually, it is (0,0,0,0), the location of the Big Bang). The past
is
inside the sphere, where it is not accessible to us.

Which means that in one second we will be almost one lunar distance
outside this sphere? Since outside the sphere is where the future is.

To be fair to him, this is what the late 'Androcles' drew attention to but in a world without attribution, at least he tried.

What a waste of mental energy but then again, theorists and their followers don't seem to mind chasing each other around in circles.
