So you're speaking of the term "religion," not the concept itself? From that very same article you linked...
"Hinduism is one of the most ancient of still-active religions,
[129][130] with origins perhaps as far back as prehistoric times."
"
Jainism, taught primarily by
Rishabhanatha (the founder of
ahimsa)
is an ancient Indian religion that prescribes a path of
non-violence,
truth and
anekantavada for all forms of living beings in this universe; which helps them to eliminate all the
Karmas, and hence to attain freedom from the cycle of birth and death (
saṃsāra), that is, achieving
nirvana. Jains are found mostly in India. According to Dundas, outside of the Jain tradition,
historians date the Mahavira as about contemporaneous with the Buddha in the 5th-century BCE, and accordingly the historical
Parshvanatha, based on the c. 250-year gap, is placed in
8th or 7th century BCE.

"
Buddhism was founded by
Siddhartha Gautama in the
5th century BCE."
There are more, but these are just a few samples that religion itself is not a modern western concept. It appears to go back to the prehistoric Indian subcontinent.
