Every single invention or bit of technology developed in the last few centuries is underpinned by accepted science which is 100% consistent with the heliocentric model.I'm fairly confident some will know what's what with an alternative to the global nonsense (in my opinion) we're fed.
There's always a theoretical horizon as long as there's light back to your eyes.
You can't escape that fact.
Transport, medicine, meteorology, building design, power generation, electronics, computing, navigation, communications and literally everything bit of kit you use on a daily basis, is as a result of hundreds of years of progress in the accepted scientific model.
You don't or can't realise this of course because you are demonstrably scientifically illiterate*, but every time you communicate with the rest of us on this forum, you are actually debunking your own position.
*this is not an insult, simply a statement of fact that applies equally to all genuine flat earthers or globe deniers.
