The world is not fair, that's just the way it is.
Some people are born in better situations than others,
for example some are discriminated against for their background,
some are discriminated against for other features,
some are born with genetic diseases and suffer all their life,
some kids lose both their parents as children and the world continues like nothing happened.
In tough situations sometimes you just have to accept that it is what it is and keep going.
People often think of other planets in our solar system like
Jupiter, Mars and Neptune when trying to answer this
but that is thinking too small and close.
The sun is a star. Just like the sun, other stars have planets
around them. Our galaxy (Milky Way Galaxy) is estimated to have between 100 to
400 Billion stars.
The probability that there is a planet out there with life in the
more than 100 billion solar systems just in our galaxy is high.
All that is just in one galaxy. scientists estimate there's between
100 billion to 2 trillion other galaxies in the observable universe.
Why does the world exist?
If you believe in the Big Bang, why was the material for the bit in existance, where did it come from?
If God exists, where did God come from?
