Question: will there ever be another living thing (not animals) which will be different to humans to act like them the same way (walk, talk, read, write)

David Foley answered on 15 Nov 2014:

Lots of animals walk and talk. Some can also communicate in other ways, such as smell, instead of reading and writing. There are plenty of animals that can use tools of various kinds to help them find food. Given enough time, evolution will increase the intelligence of these species to a point where they will become more like primitive “humans”, which can probably be typified by the harnessing of energy – like fire – for their benefit. Of course, by that time we will also have evolved (or become extinct), so we will probably never encounter a species like us from this planet. Other planets may have alien life that is of a similar intelligence to our own, perhaps superior.
