Borobudur temple (java) Indonesia

Borobudur temple one of the most beautiful and the biggest temple of budhism located in Indonesia in java of borobudur province. The temple is a unesco world heritage because of its extra ordinary and extra terrestrial design of the late 8th Century. It was build by the sailendra dynasty. And the architect that they belive was Gunadharma. The most amazing and shocking fact about this temple is that this is a huge temple to build in the late 8th century by only copper and low caste iron metal. And had no paste for connecting stones and concrete. The Temple is build in three level according to the pilgrims.
Three levels symbolic of Buddhist cosmology -
Kāmadhātu
(the world of desire),
Rupadhatu
(the world of forms)
Arupadhatu
(the world of formlessness). These great thinking was based upon the budhist and hindu theory by which who can able to pass these three levels he/she can attain Nirvana. And the temple have a big huge beautiful stupa in the centre of the temple and around that 505 budha statues in lotus position inside vajra and stupa.
The work to do in this huge great scale in the 8th century is impossible. And the Temple is mainly based upon the hindu architect and theory. Hindu  religion can travel to this far from India? This question eating up your brain i know. The same here's with me. But chill we have Alot more reasons to think about.
First of all look the picture that I've posted this is a aerial view of borobudur temple. Isn't it great nice and beautiful according to scale, measures and approximate design in this picture you can see the aerial view of temple describing a mandala. But for whom the temple  architect maked this approximate design mandala that is only  visible from sky or air or Universe i think. Yes you got it. It's the universe thing. This is a sign this Temple is a sign for the extra terrestrial of the space. By which they can still sees the sign from the sky and they wants to realise them that their culture or religion i mean the aliens things. Is alive on the planet earth and you could come here to Serve us once again.
This temple could be the space craft landing zone of the extra  terrestrial of that age. According to many locals folk tails. They said that there were many u.f.o sightings in the Temple area in past and as well as in present days too.
