A general over view of what you get by just looking out or up.

Climate change has affected our planet for many of years since day one of the Big Bang we are talking of bilions of years here even that bang bit is debatable.

The chicken and egg theory .
Ask you self what type of matter or energy came before or be in existence in order to create the Big Bang ? some say started the size of a pin head.

All you have to do is study the universe to get some of your assumptions turned into confusion relating to the universe enormity .

Our Suns light take 8 minute to get here , heat takes little longer ..

You may find planets none of which is livable by any bodies standards , either too hot or too cold , with no sign of life.

No Boogy men. !

Our Moon is comprised of left over bits when another planet crashed into Earth.
Earth is 13.2 billion years old man kind have been around for 2 billion years.

The nearest star to earth . ( we call it SUN ).

There are star bigger than our Sun do the same thing having collisions this is caused by magnatism and gravity.
Recently two enormous celestial bodies of a size beyond human comprension with a flash of energy billion time that of our Sun. collided.
When two black holes so enormous as they consume planets collide an become one the amount a power or energy released becomes unimaginable.

With the on going expansion of the universe in time our galaxy the Milky Way and that of Andromida.galaxy are destined for collision which will consume planet Earth
