We need faith to believe in anything different from our own consciousness
here-and-now.
But our perception (part of our consciousness) provides evidence for 1 universe.
?
No, only for a universe. Not one. On the contrary, the evidence is that each big things
we tought could be one, appears to be multiple: one earth => many planets, one solar
system => many stars, one galaxy ==> many galaxies, one cluster of galaxies, many
cluster of galaxies, ... "One universe" is already a strong metaphysical assumption.
I didn't assume one. I didn't make any assumption at all. I just pointed out that we
have direct evidence for one, and not for other numbers. So it is not unevidenced faith
to believe there is one. To be sure all observation includes Descartean doubt, but that
doesn't mean it's not evidence.
