"We all accept that everything started quickly"
All of us? Not really. Many only regard this as a very reasonable possibility.
"We work hard to have a safe and happy 'future'"
Very reasonable.
"We accept that the current universe has a finite life"
Very reasonable. Lines up with what we know, but not certain.
"We care about the wellbeing of others"
Of course.
"We accept the notion of an Intelligent Designer"
Not all of us do. Some of just claim that they have no evidence for such a notion.
"Main difference is that atheists have difficulty accepting Christ"
Depends what you mean by accepting Christ. Christians see Christ as the Saviour, Muslims as some sort of prophet but inferior to Mohamed, and Jews and some atheists as an historic figurehead who issued some moral directives.
"If atheists are right then no one has a bad ending"
Depends what you mean by a bad ending.
"If creationists are right then many will"
Some do, but not all. A belief in a creator is not necessary a belief in a celestial judge.
