How do we get off the planet earth into space.

How do we get out of here? Big companies are looking to get us into space. But how will we build a big enough rocket to get hundreds or even thousands of us into space. What if the planet ended and tried to turn us all into dinasaurs. We don't want to to turn into dinasaurs. We need to find a way off the planet.

What can we do?.....

How do we get the money to go into space?

I don't know how to find or build a billion dollar company. Wouldn't that be nice to create a huge company that could spend the money to get us into space. How do we build a habitat in another planet and grow are own food. Will we have to grow food and haul it by spaceship up to Mars? How will we live on Mars and breathe. Who's gonna build a city on Mars?
