In gas clouds isn't it possible that the vacuum of space is a
falsehood? Then flying creatures of all forms may come and go as
amoebas or whatever, just flitting about in a gas cloud without a care
how long it takes to network up or head on out. Planetary forms are
then optional.


I don't think so: the actual densities in the gas clouds we see in our
Galaxy are on the order of the 'hardest' vacuum that can be created in a
laboratory, or even lower. You occasionally hear of things like the
detection of X zillion tonnes of ethanol or whatever in a nebula, but
distributed through a volume in the cubic parsecs it's extremely thin,
in the molecules (not moles!) per cubic metre.
