Created does not necessarily imply a separate agency, as in "stars are created out of the dust of exploded stars", nor does form necessarily not imply an agency, as in "the child formed a castle out of sand".
Young stars mainly formed from the abundance of hydrogen, with less of other elements, eg helium, carbon, nitrogen & oxygen, but also debris of heavier particles, such as dust.
With the presence of these elements already existing molecular clouds of these elements (but mainly hydrogen), then a supernova triggering Stellar Nucleosynthesis of any star’s core, these stars are not made from nothing.
Nothing required nonexistence of any substances whatsoever, not clouds of (mostly) hydrogen (in either of gaseous or plasma state, but more likely in plasma state).
Do you understand the reason why I have continuously singled out hydrogen?
It is because that what most new stars are mainly of, in the different layers of a star, with the core being the most dense and hottest region or zone of a star, where thermonuclear fusion of hydrogen nuclei to form into heavier elements, like helium in our sun core, but stars much more massive than our Sun, they can fused into carbon, nitrogen or oxygen. Nuclear fusion occurred naturally within any star’s core. A star and its Nucleosynthesis process cannot happen without hydrogen, and the core being dense enough & hot enough, and hot as in above the 5000 Kelvin for hydrogen fusion to helium Nucleosynthesis, but much more hotter to fuse those other elements, heavier than helium.
When stars explode, it is mainly due running out of hydrogen to fuse, and a massive star is not mass enough, nor hot enough, to trigger fusions of helium or heavier elements (eg carbon), so this star continue to collapse due to its own gravity, until boom - a supernova explosion occurs.
Such supernovae are responsible for fusing elements that are even heavier than oxygen, all the elements of the periodic table, up to iron. The spreading of these other elements are responsible for formations of asteroids, moons and planets.
The formations of new star systems (stars with new planets, moons and asteroids), are never made from nothing.
More importantly, none of these galaxies, stars, planets and even life on these planets, don’t require external agencies, especially supernatural entities, like Spirit or God, fairies, etc. Hence, no Creator or Designer, not even your transcendent consciousness or universal principle that you called Brahman.
