Surely, you can provide me with just one video of it being assembled
There are many hours of video of pretty much every module being added to it over the years and the fact that you don't know that pretty clearly shows you're not interested in the truth.
Or even how they got that crap up there
Rockets. Duh.
how they got it to that speed
Again, rockets. They burn fuel at very high temperatures, hot gases expand and can only escape from the nozzle at the bottom, this causes it to come out at very high speed, pushing the rocket up, then horizontally as it gets higher.
how they catch up to it
The same way they got it up there but with extra math. Also they don't catch up to it so much as aim in front of it, generally.
maybe just an explanation of how it doesn't hit any space junk ever if there is over 10,000 pieces.
Uh oh you've actually got me on this one. I can't explain how it never collides with space junk. Actually it should be colliding with at least a few pieces of space junk every year. Which it does.
Space is huge, mind-fuckingly huge. So it's not like they're flying through a gauntlet of debris.
That being said, however, the ISS actually does have to move out of the way of detected objects to avoid collisions from time to time.
It is called "Orbital position". Geosynchronous satellites are much higher and the ISS is in a lower no geosync orbit. Other junk from early flights are at a different altitude above the surface of the earth. Persistent space junk is persistent because it stays in its orbital position. Junk that changes altitude falls to earth and burns up. The US Space command tracks every piece of space junk in orbit and plots its trajectory. There is over 100,000 pieces of junk. if they see a crossing path with the ISS, they can move ISS out of the way by changing its position or velocity slightly. With all that said, micro meteorites strike the ISS with regularity. It is designed for this. When astronauts spacewalk, they avoid touching the structure as these impacts leave razor sharp edges which could cut spacesuit gloves.
Ah they use solid fuel rockets? They have enough energy for that? How do they change direction with solid fuel rockets?
Sometimes. Solid fuel rockets are used in boosters like the ones they used with the space shuttle and some other rockets. Main engines are always liquid fuel though, so it can be throttled. I don't know about every model of rocket used to construct the ISS but the space shuttle, and falcon 9 mainly steer with thrust vectoring on the way up, once they're high enough they have separate smaller thrusters used to maneuver in space. Those are always liquid fuel as far as I know.
