for me the big bang is just the size where gravity has pulled most of the matter together to the "point" (not a literal point in size, i'm using this i guess as the limit where density and energy create an explosion so everything is thrown outwards more like a big splat not something infintely dense the size of an atom but a blob maybe the size of a galaxy where its dense enough to start an explosion. Not everything came together smoothly in a linear fashion with uniform density everwhere and it all gets thrown out until it loses energy and stops as gravityno matter how weak from distance and over eons starts to draw it all to a cosmic blob again to repeat. the big bang really looks more like a lava lamp
inflation with infinite acceleration in growth etc i see more a circular argument, when you take one graph to a limit and get infinity and put that back into another equation you keep getting infinite things so an observation can go into on equation to get a figure that can go into others for measurable predictions etc is a sort of self test that the equations work. So it becomes a word argument when people explain with infitities its not fact . Proof: the equation break down when you use those values therefore the assumption that is a legitimately reachable value must be wrong.
I do think our interpretation of much is incorrect. We are educated (brainwashed) and raised (brainwashed) in a society structure ruled by (brainwashers). The old guard are not willing to sat "everything I ever learnt was wrong because it was done in a framework with limitations and outliers always suppressed. we are not born with any knowledge not even logic. Absoluetly everything is something we learn through experience like observation. Just because you can't explain the observation doesnt mean you throw it away. but we are taught to learn a certain way and test a certain way but if that approach has flaws then we can never reach all the answers. Too many people are Certain about things and think their (in)breeding and bank account proves it. The only hope is to remove the human race completely and let evolution rediscover intelligence. I don't see what makes us better for having houses cars and internet porn than say the ancient egyptians. it may have been unpleasant to folks at the time but look what they achieved. try build a pyramid today you'll be stopped before ever starting by government officials wanting all sorts of fees and paperwork then you'll have health and f safety squawking in one ear and environmentalists in the other. All the progress of our species and our civilization leads to bein unable to ever achieve a result.
