Why the disc size of moon and sun almost equal as seen from earth? [Spirituality & Religion]
Is it a coincidence or something else?

As Justbychance said, it's simple arithmetic.
The Sun is 400 times larger than the Moon (1.39 million kilometres vs 3,474 kilometres), but the Sun is 400 times further from Earth than the Moon is (150 million kilometres vs 384,400 kilometres).
The Moon is moving further from Earth by 3.8 centimetres a year, so eventually it'll be very small indeed when viewed from Earth.
If you'd looked at the Moon a billion years ago, it would have been enormous in the sky. Even the dinosaurs would have had a quite impressive view, and that was only 60 million years ago.
Come back in 500 million years and, sadly, the lovely tightly-matched eclipses we see now won't be happening any more.
