Can human exist as a species in the future?

Can human exist as a species in the future because of difference?

You are gonna have to define Human, exist, future, and difference. I find when I ask myself this open of a question, the following results: humans are inherently different from one another on an individual level, but holeistically we are all homo sapiens (human) as a species and could potentially mate with one another (I.e. mixed race children). That being said, if we were to send a colony to mars/into space they would adapt and future generations would evole into a different species over an extended period of time that a human of now and a "human" of then wouldn't be able to concieve viable offspring.

Humans will always exsist as a species in the history of the universe even if whatever comes next calls themselves something different from human

If the population keeps growing at its current levels then probably not.  The planetary resources will be exhausted.  It's impossible to live on other planets (all of Mars is radioactive for example).  All we have is here.
