Please provide any images of space you believe are real. This can be images of Earth, other planets, satellites, ISS, far side of the moon, Tesla in space etc. But it has to be pictures that cannot be produced from earth or a spy plane at high altitude. Personally I think all planets are shitty CGI, all moonwalking footage was in a Hollywood studio, mars is simply devon Island Canada with a red tint. We have thousands of satellites in space (allegedly), so we should have clearly real photos of just about everything in our solar system, in addition to live streams and video. Hopefully we can debate the credibility of some pictures/video.
PS Flat Earth Society is a government psyop meant to mislead anyone looking into this issue, so real Flat earthers will not share their claims.
You could think of the creator as being materially efficient. If it's just easier for it to be simulated than creating the real thing then go with a simulation.
Also, there's no way to be sure about Nesting- that is, are we currently living in a Simulation that's parts of another simulation or two (or a thousand). Regardless, a creator is still necessary as the foundational creator of the first simulation. Any successive simulation could be an artifact of a non creator though.
