Do you question the speed of light for example, or the spectrum of light that is created by focusing light through a prism?
The speed of light isn't constant, which has been demonstrated by experiments in quantum physics. I haven't looked into this too much though, just saw some experiments about it. As for the spectrum of light, that I don't dispute.
Flat earth, UFO's, Sasquatch,etc, etc, etc, are all psyops designed to make the population question the reality of what Jehovah created.
I've watched FE videos and although they make some good observations and some of their experiments throw the globe Earth model into doubt, I concluded that I'm 99.99% sure the Earth is round. I don't spend any time worrying about this debate, but I can't lie to myself or others about what I've seen. The Flat earthers aren't insane... some of their work is compelling. As for UFOs, giants, Bigfoot, Lock Ness Monster... I haven't spent any time looking into them, so I don't have an opinion.
Once you give into the possibility that any of these things are true, and accept them as possible, you now become open to any argument against the truth. It seems you have fallen into this line of reasoning.
The ONLY truth I care about is Jehovah's Truth, and I have no doubt about it. In order to give my life to a God I can't see, I needed to prove to myself He's real. I did this by looking at all possibilities and questioning EVERYTHING. I've had some experience in my life that have left me with zero doubt God is real. Next I had to search for the true God, and I only found it after studying the Bible with Jehovah's Witnesses. It's my opinion that we need to be able to question everything, even our faith, in order to make it 100%... as long as we're not doing so in an arrogant way of course. Once it's 100%, we no longer need to question it though. I believe Jehovah has no problem with us searching Him out and asking for proof of His existence... which He gladly provides. It's those who refuse to accept His proof who are open to any argument against the truth. Now I only question "facts" coming Satan's system.
I'm not sure where you are getting your 'possible explanations' of the universe, but it doesn't sound like it is from credible sources.
Who can say what's credible in Satan's system? I've seen some very intelligent people discuss their theories of what lies out in space. I can't refute them because I haven't been out there. If NASA's lying, as I believe they are, then it's anyone's guess at this point. My doubts about NASA's explanations don't place me in any spiritual danger. I won't follow a false christ who believes the way I do about space. I'll only follow the true Christ, because Jehovah won't allow those who seek Him, and call on His name, to be deceived as long as we remain humble & meek.
I'm not trying to attack you, or your ideas, just merely offering potential perspectives you may not have considered yet.
Don't worry my friend... I never thought you were. I always enjoy the opinions of others concerning topics like this. It helps pass the time.
