Should we start colonization ?

There are 2 types of opinion in space agencies, should we start to travel the solar system or we should focus in making the Earth as better as we can. Both of them makes sense, making Earth pollution free and increasing it's life span is a very good idea but any way Earth will come to an end due to inflation of Sun and the solar radiation.

A better option will be to start colonizing. I have already made article on how to colonize Mars and Venus. I will leave the link to the post later.

Why should we start colonizing?

There are many reasons for us to start colonizing

Humans being immortal
Sooner or later it is sure that humans will be immortals. Transferring human brain to cloud and cloning may be a way for humans being immortal. I had a full article in this, I will leave the link below.
If humans become immortal then we need a place for everyone to live. A better option you maybe thinking is to control birth but we should not do that. Because the trend is evolutionary and new generation is always smarter. We need new and new ideas, new Einstein and new Hawking
And immortality is not far, if everything goes as planned then it may even be during our life time. (I am just 17 maybe you are older, then you will be the last generation to die. LOL

Today's granny maybe the last granny Earth will see.

Dying Earth
Stephen Hawking predicts that if we continue the same way then we only have 1000 years to live on Earth. Even if we make a great come back and stop global warming completely then also solar inflation will kill us on around 100,000 years. So if we want to live till the end of the universe then we must go around and explore.

Searching intelligent life
We may find intelligent life just close to us. There may even be life inside our solar system which we were completely unaware of. This in sharing technology between us and we both may be benefited.*
