Atheist = a person who disbelieves or lacks belief in the existence of God or gods.
An Atheist has no universal response to:
We all accept that everything started quickly
We work hard to have a safe and happy 'future'
We accept that the current universe has a finite life
We care about the wellbeing of others
But "accepting the notion of an Intelligent Designer???" If an atheist does not believe in the existence of gods - who would be this designer? Nah....
