How do we know space exists

what I mean to say is, assuming none of you have ever been to space, how do we know it even exists? Sure we are sent back amazing pictures of galaxies, nebulas and stars from telescopes all the time that wouldn't be able to be seen from earth, we have apparently been the moon, theres apparently no intelligent life in our solar system, but we are all told this from the government and the media

the universe amazes me everyday... but what if its all a lie made by our governments and space agencies?

Have any of you gone to the moon to see that it is really 407,000 km from earth? how could you be sure its not just a "small" sphere of cheese just 20km up in the sky?

First of all, what motivation would all the governments and media of the world have to maintain such a curtain of deceit over everyone else in the world? It would be a massive, multi-billion dollar ongoing nightmare for governments and media to keep the lie going year after year. It just doesn't make sense that they'd want to expend such incredible resources for a conspiracy that really doesn't have much purpose.

Also, of all the people who have ever worked for a government or media and have retired, quit or been fired, it would just take a very small handful of these ex-employees to 'spill-the-beans' and tell all. Yet this has never happened. I find it hard to believe every government has been 100% successful at silencing 100% of these ex-employees over the decades.

For these two reasons alone, I opt to believe space is real.

However, there is a much larger question you touch upon ..

How do we know *anything* exists??? I've never been to the Antarctic, and I'm not convinced it exists. The Great Pyramids - I've not seen those either. What about history? How do I know Hitler really existed at all? Or the Roman Empire? Or all the Yankees World Series victories? Please tell me those were all faked!
