because they feel like it
The humans evolved in 2000. They evolve if they visit other planets and survive without air. They evolve into a 7 foot tall green creature.
Potentially yes. We do not have the technology to get people out very far (maybe as far as Mars at present, but even that's debateable), but in theory we would be able to visit extra-solar planets as technology improves in the future.
The history of the planets had nothing to do with humans. Humans used the planets as religious symbols.
We dont currently have the technology to get them there. They are very far away - several decades of travelling, even at the speed of light.
No, the Earth is the only planet with Humans.
Very probably
Humans can live on the planet Earth. Other planets are unsuitable for our existence unless new technology was able to assist humans in harsh environments.
A geologist might want to be an astronaut to study the geology of various planets and moons. The moon and perhaps, some day, Mars are candidates for geologists to visit.
no. no humans have ever been to any of the other planets.
because it has humans in it and humans need light
Nothing in the positions of the planets affects humans. There is no proven connection between planetary activity and any individual's life.
yes
