The closest star, Alpha Centaury, is four light years away. If light travels 300,000 kilometers in one second, it would be necessary to calculate how many kilometers it travels in four years to know how many kilometers Alpha Centaury is from us.
300,000 x 60 = 18,000,000 kilometers in one minute.
18,000,000 x 60 = 1,080,000,000 kilometers in one hour.
1,080,000,000 x 24 = 25,920,000,000 kilometers in one day.
25,920,000,000 x 365 = 9,460,800,000,000 in one year.
9,460,800,000,000 x 4 = 37,843,200,000,000 in four years.
37,843,200,000,000 kilometers away is the closest star to us, (the others are thousands of times further away) a species capable of covering such distances would have knowledge and skills that would apply it to doing things much greater than playing hide and seek with a primitive species.
