• Somehow, this outwardly blasted material manages to gather and clot sufficiently enough to generate enough gravity.
• The above process only lasts long enough to not become an all consuming mass hurling through space.
• Gasses did the same as the solid matter, gathered into clumps, gathering enough mass where gravity could squeeze it into ignition.
• Somewhere along the way it all got to being organised and conducive to life forming.
• Life did eventually form.

• An intelligent being on purpose caused the big bang as part of the creation process .
• Life on Earth was part of the same creation process.

Item 1} The matter ejected by the bang - an explotion - somehow formed clots big enough to produce their own gravity, but not endlessly gathering mass...
This makes the new assumption that Physics are not yet a law, that despite the outward force pushing everything away, some of the matter could start to clot and amass.
Also assumes that there was always just the right amount of matter to form nicely sized planets.
Gravity increases with mass . . As these masses grow, their reach extends. Surely this process would run away.

Item 2} This would have to happen in the very early stages. Distance only increases with explotions.

Item 3} Gases did the same.
Gasses don't move to a higher pressure without force.

So, if we're going with the fluke forming planets and stars, be it by gravity or by some other anomaly, we need to move on to our next assumption.

Item 1} Intelligent creation.
If an intelligent being created the universe, that would make him a God.
Item 2} Earth was part of that creation.
This leads to the next new assumtion...

• Physics weren't a thing yet.
• The formed planets just kinda settled into perfect orbits around stars.
• These solar systems went on to organise themselves into galaxies.
• Life evolved from basic materials.

• Creation was done with the materials produced in the bang.
• There was purpose and plan.
