According to archaeologist JR Bhagat, these paintings have depicted aliens like those shown in Hollywood and Bollywood flicks. Located about 130km from Raipur, the caves come under village Chandeli and Gotitola. "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," Bhagat said.

There are several beliefs about these paintings among locals in these villages. While few worship the paintings, others narrate stories they have heard from ancestors about the "rohela people" — the small sized ones — who used to land from sky in a round shaped flying object and take away one or two persons of village who never returned.

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. Specially, 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," the archaeologist said.
