"The theory of gravity is just a theory."

are you really putting the big bang up against something like gravity as a comparison?

"A scientific theory is something that has been observed, has evidence, working models."

no one has observed all of the matter of the universe springing from a singularity

you can't model a singularity

to compare this with gravity is really reaching don't you think? since we can observe it directly and can model the acceleration of 9.8 m/s

 

I think you raise a good point.  Singularity is just a consequence of the Big Bang model.  But because the Big Bang model describes the observable world so well, it makes sense to explore its consequences.  I wouldn't consider it as a "belief" in the singularity though... it just means that it's within the realm of possibilities and has not been disproven yet.  

And also, a quote from your first post:

Atomic bombs, nuclear bombs, tanks, assault rifles, war planes, aircraft carriers, biological weapons... these are all technological devices created by science for one purpose- to end life

These are more engineering developments.  Science explains how the universe works, engineering is how to use it.  

i'm not even saying that i think the theory is wrong or whatever, i just wouldn't put it on the same level as gravity since there's less evidence we deal with directly
