Atlantis, Lemuria & Pangaea

Atlantis is one of my favorite undiscovered ancient civilizations. 
There are many theories about Atlantis & where it might be, I think it is where the map shows it is below.
My theory, is that beings from another world came to Earth, settled in what they thought was the perfect area & thrived for many years. I think they scouted the Earth & found what they needed including a human woman to help create a perfect mix of alien & human beings. Then a natural disaster destroyed what they had created, scattering them all around the world.
Plato wrote much about Atlantis & I will share some of what he wrote, along with a map I find to be very interesting.  Also take note of the fact that he talks about a God mating with a human woman & having 5 sets of twins... sounds like genetic testing to me!

Over 11,000 years ago there existed an island nation located in the middle of the Atlantic ocean populated by a noble & powerful race. The people of this land possessed great wealth thanks to the natural resources found throughout their island. The island was a center for trade  & commerce. The rulers of this land held sway over the people  & land of their own island & well into Europe and Africa.
Atlantis was the domain of Poseidon, god of the sea. When Poseidon fell in love with a mortal woman, Cleito, he created a dwelling at the top of a hill near the middle of the island & surrounded the dwelling with rings of water & land to protect her.
Cleito gave birth to five sets of twin boys who became the first rulers of Atlantis. The island was divided among the brothers with the eldest, Atlas, first King of Atlantis, being given control over the central hill & surrounding areas.
At the top of the central hill, a temple was built to honor Poseidon which housed a giant gold statue of Poseidon riding a chariot pulled by winged horses. It was here that the rulers of Atlantis would come to discuss laws, pass judgments, & pay tribute to Poseidon.
To facilitate travel & trade, a water canal was cut through the rings of land & water running south for 5.5 miles (~9 km) to the sea.
The city of Atlantis sat just outside the outer ring of water & spread across the plain covering a circle of 11 miles (17 km). This was a densely populated area where the majority of the population lived.
Beyond the city lay a fertile plain 330 miles (530 km) long & 110 miles (190 km) wide surrounded by another canal used to collect water from the rivers & streams of the mountains. The climate was such that two harvests were possible each year. One in the winter fed by the rains & one in the summer fed by irrigation from the canal.
Surrounding the plain to the north were mountains which soared to the skies. Villages, lakes, rivers, & meadows dotted the mountains.
Besides the harvests, the island provided all kinds of herbs, fruits, & nuts. An abundance of animals roamed the island.
