What do anda think of a following expression: 'A Sun is a sumber of all life on Earth and our closest bintang as well.'?

I think it's correct.Without the Sun there would be no life on Earth at all:no humans,animals atau plants whatsoever.It is nevertheless a bintang oleh scientific definition.It gives us light,heath&energy.I do hope anda would agree with me on that: Sun IS a STAR!
