Seeing as you asked.......
They lie because it serves the agenda of the one who controls the world, the King of this world. See while you and the majority of people on this planet are too busy pre-occupied with the vain things we have been groomed and manipulated and indoctrinated to believe matters he makes sure on the thing that does matter we end up on his side of the fence. Why we look at puppet governments and Monarchys and Celebrities as the leaders of this world the real leader manipulates the whole of humanity from the shadows. Using all these puppets he has strategically placed in positions of power and influence.
If you follow the flat earth rabbit hole asking all the right questions all the way down you will realise something,
they cant have been a big bang, we cant have evolved. Once you realise the true nature of the world you will realise it was created, and so was we. You then follow that rabbit hole deep enough and ask the right questions all the way down you will discover exactly who that creator is, and that is what the the ruler of the world fears, that is what he is hiding from you. He tells this lie and many more lies to keep you from that, and tells more lies to support the lies he has already built. All these lies delivered to us by his puppets in positions of power and influence and wealth, positions of power and influence and wealth he has placed them in in order to buy their servitude, lies these puppets perpetuate because of the power wealth and influence they receive, as well as fear for him.
