Do Aliens exist? Did Whistle Blower prove that we’ve been visited by extraterrestrials?

Are Aliens real? Who do we believe? What does it all mean? With the bombshell news of a whistle blower saying that UAP's are legitimate and the government has been hiding this from the public, what does it mean? Who are they? Where do they come from? Beginning in 1918, occult magic practices were claimed to be responsible for opening a tear in space time fabric, allowing inter dimensional beings to enter our reality. Is this true? Is there a connection between this claim and the great UFO flap that began in 1940's? What is the agenda behind revealing this information now?
