>They are unknown
Not according to the big bang model according to that the current conditions have been traced back to the initial conditions which are massless.
>leads to a single point.
Yes a single 0d point which means by the theory, no mass existed and according to the theory, it didn't exist until the electroweak epoch.
>You are simply extrapolating, not measuring these conditions, you cant measure them.
Correct, the big bang theory is not a measurement.
>And these extrapolations say the early universe was like ours but hotter and more compact,
No the extrapolations say it was nothing like ours until after several epochs, the electroweak epoch being the one that conferred mass to the universe.
> not some kind of pure energy soup that then became matter.
Wrong, learn about the epochs, planck epoch, grand unification epoch, and rapid inflationary epoch were nothing like our universe and did not contain matter.
