it started couple of years back with a clip on youtube & I thought what idiots would believe its flat and I thought it wont take me longer than a couple of minutes to proof its round...

here are a few points
1. water doesn't bend - Chicago across the lake for example, varies laser experiments over flat waters (discovery channel is never going to show you if its flat) I looked at privately done ones and multiple of them.
2. high altitude balloon (again - looking at the hobby person launching it to 120k feet or even higher with no curvature insight) Sure you wouldn't see a huge curvature but Nasa shows at 70k feet a massive curvature. Redbull jump for example was also doctored with - stickers didnt line up to previous shots on the ground.
3. Moon and eclipse - countless times which has been documented & filmed where both - the sun and moon are visible at the same time and the shadow going over the moon. Now this wouldn't be proof that earth is flat but it doesn't proof its round either.   
4. Climate - North pole vs South pole & comparison in between. North pole is -3 or -4 degrees and South Pole is -50 degrees average. If same exposure as per the heliocentric model one should see at least values a bit closer...
5. 24hr Sun at South Pole - couple of videos were shown as proof that there is 24hr Sun at the South Pole which turned out to be doctored/ tempered with. Suspicious
6. Antarctic treaty/ Nasa
7. the huge amount of blunders from Nasa & the ISS (quite disappointed as I was a fan of it)
 
It takes an open mind and a lot of reading of different literature. Once the penny drops though the current state of where we are as humans becomes clear or more understandable. From War to climate change, the financial system, Religion etc.... I have come to the realization that its slavery.
