Research done. We've sent thousands of rockets into space. Now, tell me how that did not happen.

Now once that same rocket enters the vacuum of space the gasses are now open to a vacuum. The gasses will expand and escape but without doing any work. So in 1969 when you saw the LEM taking off from the lunar surface you saw what looked like a gas expanding and produce propulsion which is work, to lift the LEM off the lunar surface to then rendezvous with the CM. That scenario is scientifically unsound. Gas exposed to a vacuum cannot sustain a reactionary force to do work. So no, we didn't go to the Moon in 1969 or beyond.

That is the the most stupid thing ever posted. The laws of physics work in a vacuum. So there's been no Sputnik, no Voyager? The Juno probe is not now orbiting Jupiter? There was no Mercury, Gemini or Apollo program? Elon Musk and Richard Branson are spending millions of dollars on commercial space travel that is impossible. Tang was never invented?

Which all come into play in space travel. Nothing has been put out past Earths Orbit, which there still is a degree of air density however slight. Rocket propulsion is designed to work in the presence of air without it they don't work, it's that simple. If you think the Government lies to us well NASA is a Government Agency. They sell space travel. We believe them because, hey their NASA. Space travel outside Earth's Orbit isn't possible with todays technology.
The gas in the rocket is expanding. It escapes through the easiest route, the nozzle of the rocket. That creates thrust. It's not pushing against anything. Newton's Law says that if there is a force going one way, there must be a force going in the opposite direction. IT DOESN'T HAVE TO PUSH AGAINST ANYTHING! The reason Challenger exploded was because there was a weakness in an O ring, creating a point of low resistance that wasn't at the nozzle. Then it exploded. It didn't push a different direction.
Rockets are a controlled explosion. When you shoot a gun, and feel that "kick", that's what happens on a much larger scale in a rocket. The bullet doesn't "push" against the air to get to the target.
You are a flat earth fool. The Bible is not a science book. Originally Posted by CuteOldGuy

It can function in the vacuum of space just as easily as it does in an atmosphere containing oxygen.
