I have seen the hardware up close and have watched actual manned rockets launch. All of the physical evidence makes sense to me. all of the fuel management systems which include variable flow regulators, compressors, heat exchangers that utilize heat from rocket nozzle to accelerate the thermal expansion properties of LOX. Huge tanks which have the proper volume ratio to carry the gases which produce flame propogation for the duration of the burn
for excelleration of the neccesary payload. The decreasing mass and support structure as you build up the vehicle. The life support systems. Too much for it to be pretend. The list is endless.
