To add to your point, why should there be nothingness? Who is to say that 0 is before 1? There's 1/2 somewhere right? And 1/4 before that, etc. It's not obviou

To add to your point, why should there be nothingness? Who is to say that 0 is before 1? There's 1/2 somewhere right? And 1/4 before that, etc. It's not obvious that there "should" be nothing, rather than perpetual something. It's not obvious we should work with integers and not the reals. Or the rationals. Or the rationals without zero, which cannot exist as a denominator (in the common definition of the rationals). It's not obvious that we've ever detected zero. And why a line? Why not a circle? And even if a line, couldn't it be the limit of a circle whose radius tends to infinity? Etc.
