Indian archaeologists said they have discovered 10,000-year-old rock paintings of aliens and UFOs in an ancient cave, situated in tribal Bastar region of the Indian state of Chhattisgarh.

The Chhattisgarh state department of archaeology and culture is planning to ask Nasa and the Indian Space Research Organization to study the rare "alien paintings" from the prehistoric period, the Times of India reported.

The paintings have been discovered by archaeologists in a remote tribal Indian village called Charama.

"The findings suggest that humans in prehistoric times may have seen or imagined beings from other planets which still create curiosity among people and researchers. Extensive research is needed for further findings. Chhattisgarh presently doesn't have any such expert who could give clarity on the subject," archaeologist JR Bhagat told the website.

Tribal villagers are known to have worshipped the "suspicious" images in the paintings which their ancestors have described as the "Rohela People".

The ancestral legend goes like this: some small sized people would land in the village and take the villagers with them in a round shaped flying object.

Archaeologist Bhagat also claims that the paintings are of natural colour and have strange pictures depicting people in spacesuit-like attire.

"The paintings are done in natural colours that have hardly faded despite the years. The strangely carved figures are seen holding weapon-like objects and do not have clear features [...] the nose and mouth are missing. In few pictures, they are even shown wearing space suits. We can't refute possibility of imagination by prehistoric men but humans usually fancy such things," Bhagat told TOI.
