Whereas most modern religions teach that when a person dies, the soul progresses to an afterlife in heaven or hell, or is re-incarnated in a new life on earth, secular belief is that there is no afterlife. We will live on in the memories of our loved ones, friends and acquaintances.
Atheists have the same view about friends as everyone else.
Any atheist is a person who simply doesn't hold a belief in a god or gods. As such, he or she could have any belief about suffering or death, because atheism is not a belief, and it is not dogmatic.
That is not a question. Atheists view friends as friends.
Since atheism is the lack of belief in deities atheists do not blame gods for anything.
The same as anybody else would.
Many Buddhists are atheists yet also believe in reincarnation, so yes some atheists believe that people live again after death.
Atheism is an absence of belief in a deity, so there isn't a doctrine of beliefs as you find in religions and there isn't a single thought or belief about death which is shared by atheists. Some Buddhists are atheists - but believe in reincarnation, other atheists believe that when we die, we cease to be.
This does not really have to do with extentialism, But we atheists view sexuality as a healthy part of an adult's life.
There is no single view of knowledge held by atheists because by definition, Atheists are people who do not believe in any higher power, and that is their only uniting trait, everything else can be widely varied.
== Pretty much. == Yup. == Atheists do not claim to know for certain what happens after death. For a skeptical person "I dont know" is a perfectly acceptable answer, and is greatly preferred over any amount of guesswork. So most atheists will tell you that they don't know what happens after death, but will also admit life after death is very improbable.
Atheists would view God as imaginary, therefore the nature of the concept would be human-originated.
In religious texts, God's perspective on atheists varies. Some believe that God may view atheists as individuals who have not yet found faith, while others believe that God may see atheists as individuals who have chosen not to believe in Him. Ultimately, interpretations of God's views on atheists may differ among different religious beliefs.
