LOL! I do believe, this planet will be taken over by Aliens eventually. Too little attention is given to taking care of the planet. People are like in a dream as regards the future to the Earth, IMO. It's like long ago, when the Spanish took over the Aztecs in Mexico, they seemd like "Aliens" to the natives there. The same can happen again, but on a much larger scale.
Just to remind myself, I looked up the story of the Spanish Conquest of the Axtecs. Here's a kids' version, which is nice and short.
A discovery on one of Saturn's moons just changed how we think about alien life
Underwater hydrothermal vents — the same kind that may have spawned life on our planet — seem to be lining the ocean floors of Saturn's tiny, water-rich moon called Enceladus, according to two recently published papers.
This is the most compelling evidence we have so far for the existence of these vents anywhere other than Earth. The latest discovery is a tantalizing hint that the conditions right for life may be present outside of Earth.
