<blockquote>By watching the video of that dude that parachuted from space, and observing his view of a curved globe.</blockquote>

That is a GoPro camera with a fish-eye lens. You would not be able to see Earth's curvature from that close. Even NASA will tell you that. Look at that video again and notice that the camera inside his pod does not use a fish-eye lens. You can see a "flat" horizon. Now look at the fish-eye lens used afterwards and tell me, how small would the Earth have to be to see that much curvature from that close to Earth. Use your head man, stop relying on what you've been told. :)

Do it and take some pictures and show us. I am interested to see how it comes out. NASA's CGI images are getting old.

Believe it or not there is also a perfectly good explanation for this if the Earth was flat. But it requires an open mind and research. You must throw away the indoctrination for a few minutes and allow yourself to learn of other possibilities. 

<blockquote>By travelling to an "edge country" and observing buildings in the street</blockquote>

It is called "perspective". Artist use it all of the time on a flat piece of paper. ;)

<blockquote> If I didn't feel gravity tugging me back towards the centre of the Earth</blockquote>

Up and down is different from forward and backward. You are saying that if you walked towards the "edge" you can feel the Earth pull you back to the center of the Earth? I think you are confusing two different directions to make your point. There are also these things called "mass" and "density" that could also answer the "feel" that you have.

The ISS is a whole new can of worms I do not think you are ready for yet my globalist friend. But it is some cool imagery. I will give you that.

<blockquote>Sorry one more! In order for gravity to work the way it does on Earth, he sun would have to be 32,000 miles away and a lot smaller than it actually is. This would be fairly easy for an amateur astronomer to verify.</blockquote>

Really? How easy would it be? So easy that they have changed the distance the Sun is from the Earth how many times now? That dang math! Is it just a coincidence that the Moon is 400x smaller than the Sun and the Sun is 400x farther away from Earth than the Moon and that's why they appear to be the same size to us on Earth?

These are just a few of the questions you can ask instead of believing what you have been told. When we begin to think for ourselves and do our own experiments our minds really being to open up from the closed indoctrination we have been served our entire lives.

Science is about questioning things, not accepting what we are told as the truth. Do not be afraid to question! You have obviously bought into the indoctrination and have been taught to ridicule anything questioning your indoctrination. 

We are all taught this as kids. Make fun of the other kid that questions anything the teacher says. Make that kid feel stupid and call them names and repeat what the teacher has told you. Isolate that kid until they stop saying things that are different from the indoctrination.

It is a sad state of affairs to see that in today's world we still have people doing this same thing into their adult lives.
