Premise is spelled with an e.
The sun HAD to be larger. It's on fire! The fire that creates the heat from our sun is burning something. Gaseous mixture ratios have to be within a certain range to burn, thus a further argument for its shrinking to maintain density equilibrium. Similarly the newest era of missles that sucks out the O^2 from the atmosphere creates suction. Review the laws of thermodynamics and physics and then we can talk again.
