I doubt these are ETs. They have demonstrated capabilities that we have no defense against.
Your logic is good.
But there are no ET’s.
Absolutely right. IF it’s aliens.
They are far past our military capabilities and it would be like when we encountered the primitive and backward Native Americans who had sharpened stone arrowhead and wooden spears while on horseback and we had rifles, pistols and cannon and soon Iron Horse railroads.
Even if they were ET’s..... WHY would they land here lol.....
