There is a picture often being spread on social media with the claim that an ancient carving of Lord Varaha shows him lifting a globe Earth hundreds of years before modern science had come to this conclusion. The following picture is one example of what is being sent:
When you look at a clear closeup photo, it is actually a shankha (conchshell), not a globe. The shankha (conch) and chakra (discus) are being held in the Lord’s two hands as His weapons. It has nothing to do with a globe Earth and He is not lifting it with his nose. On the far left side is the matching chakra that goes along with the conchshell on the right.
The Earth is represented by the female Devi He is lifting. In South Indian temples Bhu Devi (Earth) is always shown in human form with Lord Varaha. She is Goddess Lakshmi.
The temple carvings them self are also not necessarily ancient (though some may be), as the temple was restored in recent times. You can see in a picture from 1855 and one from today that the entire temple dome was remade along with many other parts of the temple, as it had been lying in complete ruins for centuries.
We should not perpetuate false statements with an intention to make our dharma “look better” or “more scientific”. The Vedic knowledge is already as brilliant as the sun:
kalau naṣṭa-dṛśām eṣa
“This Bhāgavata Purāṇa is as brilliant as the sun. Persons who have lost their vision due to the dense darkness of ignorance in the Age of Kali shall get light from this Purāṇa.” – Bhagavata Purana 1.3.43
The sun needs no external illumination. Trying to improve or make the Vedic knowledge appear “better” is like a glow worm trying to shine light on the sun, which is itself the source of all light.
