Because to get to one of those planets you weed need to travel about 4 light years (The distance olight travels in a year). We can currently travel at about a thousandth of thwe speed of light, so unlesss you want to wait 4000 years, its not possible.
It would be impossible for humans to land on Jupiter, Saturn or Uranus. As a group, these planets are referred to as "gas giants". If any of them has a solid surface at all, it lies beneath thousands of miles of gas or liquid, in total dark and under temendous pressure.
None of the planets in our solar system have an atmosphere that is breathable by humans. The only known celestial body with a breathable atmosphere is Earth.
as far o what in aware of they have only gone to the moon, but have sent robots to vistet oher planets. i
NO>Planets are not as near as they appear to be and it takes lot of time, money and resources to successfully send a human and bring him back safely. It is very like that in the coming 2 decades we will be able to send humans on MARS which is the one of the nearest planet other than venus.
No, humans have not landed on any planets besides Earth. The main reason is the extreme distances and conditions of other planets in our solar system, such as harsh temperatures, lack of breathable atmosphere, and intense radiation. Sending manned missions to other planets would require significant advancements in technology and resources.
It would be impossible to land on Jupiter, Saturn, Uranus, or Neptune because none of these planets have definite surfaces.
Th answer is not yet known. There are, at present, no known exo-planets which can be reached using current technologies for space travel, life sustainability and so on. It is possible that the technologies will increase our range and new exo-planets will be found. Personally, though, I believe that humans will destroy the earth by polluting it long before our science and technology can do that.
No one knows exactly as the first technologies predate modern humans by millions of years and it is impossible to know what our ancient prehuman ancestors were thinking back then.
Because humans are humans and every human that has ever lived has used at least hundreds of different technologies every day of their lives. The earliest humans used the technologies developed and used by their direct prehuman ancestors. Humans will always use technologies and develop improved technologies.
The history of the planets had nothing to do with humans. Humans used the planets as religious symbols.

no
It explains why the planets remain in in orbit around the sun. Also, why moons orbit their planets. It also explains why humans remain on earth.

As humans were not around to hear living dinisaurs it is impossible to answer this question.
No, the Earth is the only planet with Humans.
Very probably
