Yep, huge clouds of gas in outer space can exert
self-gravitational forces _much higher_ than the
force of gravity at earth's surface, because they
mass at least trillions of times as much as the
earth does.

1) You sort of miss the point. The pressure required
to get started isn't the pressure required to
_ignite_ a star, at all.

The pressure required is that to get a chunk of a
gas cloud _moving toward_ a common point in space.

The closer it gets to that point, the more its
self-attraction rises, by a square law, making it
accelerate, and the faster it approaches that point,
until it succeeds in collapsing or until some other
force pushes it away. The volume / pressure law does
apply in a modified form, so that the inward falling
outer shell of the gas acts as a quasi-"container"
for the inner gases, helping confine them, letting
their pressure continue to grow, and countering
their outward pressure as they continue to collapse.

At this point, you pretty much have to learn to
understand the math at a fairly sophisticated
calculus level to follow the process to the point
where the star ignites, if it does at all.

It is quite possible, instead of a star, to end up
with something like Jupiter if the gas cloud is
sufficiently large to collapse, but not (locally)
large enough to create a star.

[By the way, Jupiter, which is all gas, and is
thus nothing more or less than "a cloud of gas
in outer space", could not exist if the nonsense
you have been spouting here were true.]

2) The self-gravitation of a lot more mass than
actually ends up in the star, since as soon as the
star ignites, its emitted photon pressure pushes the
rest of its gas-cloud-of-birth away, possibly
speeding it up enough that it collides with nearby
gas cloud matter sufficiently forcefully to trigger
genesis of more stars. Thus, in the usual case, star
births are multiple ones, taking place in a "cradle"
comprised of a large gas cloud and a lot of shock
waves transiting that cloud.

Because the speed of light is so incredibly slow,
compared to the size of a gas cloud in space, an
electromagnetic-origin shock wave can take (tens
of) thousands of years to pass through a gas
cloud, possibly triggering stellar genesis all
along its route.

It does make that law inapplicable, since it is an
"Ideal Gas Law" which does not take gravity into
account, making situations where gravity is included
not subject to any unmodified form of that law.

Again, by filling you with half truths, those who
hold you in slavery have made you fully ignorant.

> Stars are a product of creation by a Creator.

You can stop posting this blatant falsehood any time
now.

Your false arguments that physics _cannot_ explain
how stars are formed, even if they were true, do not
lend any credence to your doubly false arguments,
both that gods exist at all, and also that gods have
the ability and agenda to create stars.
