Ancient Extra-Terrestrials Advancement! Poem by Ramesh T A

Before writing came into use, arts have come;
Singing and drawing pictures in caves were there;
Ancient men and aliens have made their marks
In underground caves in South America, Mexico!
Literature has developed before grammar & writing;
On walls of caves, aliens have drawn map of Universe;
Aliens were more advanced than us in technology;
Otherwise, they could not have travelled in Universe!
Perhaps the deities of temples were Extra-terrestrials
And the temple towers were cabins of ancient rockets;
Like the forest and interior tribal men believe as Gods,
Our ancestors could have believed aliens as deities!
The inscriptions on ancient relics say a lot of their life and
Advanced developments many thousands of years ago!
