That's like saying Huckleberry Finn doesn't exist. Just because it's made-up doesn't mean it doesn't exist. It exists as a concept which billions of people understand.

The Sun's position on the ecliptic at the vernal equinox is not a "concept", it's a physical reality, recognised by the International Astronomical Union.

Disagree on the semantics. Physical realities are concepts as well. "Energy", despite being an extremely useful physical measurement, is an abstract concept. "Physical realities" and "concepts" are not mutually exclusive nor antonymous words.

In this case, the Aries/vernal point is a concept used to define coordinate systems using physical measures from Earth.
