Earth is being invaded! Not really, their just clouds!
Strange Clouds known as Lenticular
clouds (Lenticularis) but also known as "flying
saucer clouds," "angelship clouds",
"cloudships", "clouds of heaven".
These clouds and clouds of similar kind have been
reported as UFOs in cloud disguise. For others these
cloud formations can be completely different things
or simply just clouds. In the Bible there is much
written about cloudships. The Bible is referring to
some type of flying craft that possess an ability
to hover in one place for a longer time and appears
in the sky surrounded with clouds. Ancient texts describe
how pilots could using correct proportions of certain
chemicals give their flying machine "the appearance
of a cloud".
