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.
Yes, it is possible that there are other Earth-like planets in the universe. Scientists have discovered thousands of exoplanets, some of which are in the habitable zone of their star where conditions might support life as we know it. Future missions and advancements in technology may help us identify more Earth-like planets.
Studying the earth helps scientists to understand other planets since the earth is part of the solar system. Scientists use the features of the earth to compare them with what other planets hold.
No, planets do not emit energy that we can directly absorb. However, the gravitational influence of planets like the sun on Earth does affect tides, weather patterns, and the overall conditions of our planet.

to have something to look at when you can see them
The inner planets (except Earth), and in fact all of the planets besides Earth in our solar system, were named after Greek and Roman gods.
All planets in the solar system, besides earth, are airless. These planets are not able to contain human life.
