How did plants first came to Earth? How were plants made? Can other plants grow on other planets and be eaten? That would be awesome.
Answer 1:

Plants evolved from green algae during a period between about 510 and 430 million years ago. Of the planets that we know about, none of them could have any plant life. It is very likely that, somewhere in the universe, there are other planets that do have life, and on those planets there may be living things similar to plants, but not the same as the plants that live on Earth.
