The same team that theorized another black hole lurks close to the center of the Milky Way last year, have come up with more evidence of it: http://www.sciencealert.com/a-new-k...een-found-hiding-near-the-heart-of-our-galaxy
The key here though is:
But if it is, then the Milky Way may have consumed another galaxy in the past, and we may have come with it, from an alien world. Or as another article put it recently, _we_ are the aliens.

Now, the same team, led by astrophysicist Tomoharu Oka, have backed up their initial findings, using new measurements taken by the Atacama Large Millimetre/submillimetre Array in Chile.
Again, the researchers detected a distribution of velocities inside a clump of gas in the cloud, but this time they found something else too: a spectrum of radio waves, similar to the readings Sagittarius A* itself produces, but about 500 times less luminous.
The key here though is:
The researchers aren't saying the new measurements confirm that the source of the radio waves – called CO–0.40–0.22* – is in fact an intermediate-mass black hole, but they are claiming the new results offer our best, least ambiguous evidence of the phenomena to date.
But if it is, then the Milky Way may have consumed another galaxy in the past, and we may have come with it, from an alien world. Or as another article put it recently, _we_ are the aliens.
