I was going to tell you that Ovni's been around since the '60's at least, when I started researching them.
I also studied astrophysics & mathematics to the point that they wanted to send me to college for my math & science classes when I was 11. Luckily for me, I didn't go ( NASA was one of the research groups used by the CIA's MKUltra subproject 159.)
However, I went into a DEEP depression...& to this day, I have a math block (unless somebody slips me homemade morning-glory seed " LSD". Bitch. Fucked up my midterms big time. Lowest score I got was a 97 in algebra & trig. Teacher wrote " Now that I see what you can do, I expect it all the time." I had a GPA in that class just barely a 2.0.)
You don't need spacecraft to travel to other planets. Omega point technology (where you currently are is connected to each & every part of the Universe) makes spacecraft obsolete, but you don't have that technology yet...& I'm. NOT about to give it to ANYBODY.
UFO's are interdimensional, NOT extraterrestrial. They use so-called "elyectronic fog" technology.
