You didn't understand this bit. When galaxies collide they deform each
other completely, the gravity deforms. Nothing alive can survive this.

Sure, there is gravitational interaction on a scale that deforms the
galaxies and seems quite dramatic from a distance: https://apod.nasa.gov/apod/ap150201.html https://apod.nasa.gov/apod/ap180607.html
The Milky Way has probably had several of such collisions in the past
4.5 billion years, but "Stars within a galaxy are very sparsely
distributed, being separated by distances of the order of 10 light
years. In a scale model in which stars are represented by pinheads,
these would be about 50 km apart and the solar system (out to the
orbit of Pluto) would have a radius of 5m." (Rindler, 2006, p.350) https://global.oup.com/academic/product/relativity-9780198567325
The chances of any two stars colliding during such a galaxy
"collision" are very small indeed and most of them will pass each
other undisturbed.

Those things are pretty complicated, and for sure there are some other characteristics involved, the word "advanced" in that sense doesn't mean that the organism which has higher entropy is more "bullet proof", I guess.

Not likely. People who believe there is likely life on other planets misunderstnad how violent the universe is. The odds that a planet can
find a quiet corner in the universe to promote life over 4 billion years
is much longer odds than the total number of possible planets there are.

I have the same view. It doesn't have to be that simple, it can
advance somehow, yet, not enough, and the "advancement" definitely isn't
the (main) "force", we, generally, just adjust.
Though all this is pretty complicated. In any way, I don't think that we will ever have enough of whatever-it-needs-to-be to survive.
The other thing is, it is nowhere written that we have to survive, it is not us that is the center of the Universe, Universe
doesn't exist because of us.

An astronomy thread is SBP? Fascinating.
For those concerned about colliding stars during galactic collisions,
here's some factoids to assuage yourself:
<https://astronomy.com/magazine/ask-astro/2006/01/how-close-can-stars-get-to-each-other-in-galaxy-cores#:~:text=The%20average%20stellar%20density%20here,5%20light%2Dyears%20between%20stars.>
<https://tinyurl.com/p2zcyhrc>
**************************************
The average stellar density here in the galactic disk is one star
every 19 cubic parsecs, or about 5 light-years between stars. >*************************************
Even in the Milky Way's more dense central core, stars are still
separated on average about 860 AU apart, over five times farther than
Voyager I has traveled beyond the Sun. So it's extremely unlikely any
stars collide during any galactic mergers.
And if stellar collisions worried you, there's still plenty to worry
about. The Milky Way and Andromeda are about the same mass. This
means when they merge, they will almost certainly tear apart their
spiral structures, fling many stars into intergalactic space, compress

Large Magellanic Cloud is scheduled to merge with the Milky Way even
sooner, in less than 3 billion years. When it does, the two
supermassive black holes in the centers of each galaxy will merge and
form an active galactic nucleus aka quasar, which make supernovae look
like farts in a hurricane by comparison. Any nearby stellar systems,
or those caught in its twin polar jets, will be vaporized.

And if that worries you, I shouldn't mention the eventual expansion of
the Sun starting about a half-billion years from now, which will
definitely end any debate about global warming.
Sleep well.
