Do you think the Sun is big ? Well... The biggest star (UY Scuti) found yet is 1708 times bigger than our star with a diameter of 2'378'704'272 KM.
If the Earth was a beach ball (20cm) then the Sun would measure 22m and UY Scuti would be 38km long.
...But in reality, UY Scuti is small in the Universe. Our Galaxy, the Milky Way, is 336'317'552 times bigger than UY Scuti.
Anyways, you got the point. We are tiny.
