Are Atheism and Agnosticism religions?

The fundamantal premise of any religion is beleif in God.Religion cannot be described as a way of life. People do not live today the way they did in the past, they are religious nonetheless. The concept of religion usually gives a picture of beleif in god and the ritulistic practices. Atheism are agnostism are not religions nor are they 'ways of life!' They represent just one statement in the huge book of one's outlook towards life. We can further this discussion if you care to define 'way of life'

I think that defining religion as "A way of life" is bad definition, it is more than a way of life, is , perhaps, a way to interact with a powerful being (god) and to follow his rules. It is a simplistic and BAD definition, that would require more tought and development. The other problem is that the only thing that all(or almost) atheists have in common is the lack of belief. Some are called "weak" atheists, other "strong" atheists, their "way of life" differs a lot. Atheism by itself is only a lack of belief in deities, only that. The way of life needs more than a lack of belief in deities to be defined. One can think that since there is no god everything can be done, others (the majority I think), may live a life with ethic, since this is only what we have, and it is better to try to have the best life we can, and don´t do to others what we don´t want to de done with us. This is not religious, it is just simple tought and logic. By the way, I am atheist.

Atheism is the disbelief in the existence of any deities. It is commonly defined as the denial of theism, amounting to the positive assertion that deities do not exist, or as the deliberate rejection of theism. However, others—including most atheistic philosophers and groups—define atheism as the simple absence of belief in deities (cf. nontheism), thereby designating many agnostics, and people who have never heard of gods, such as newborn children, as atheists as well. In recent years, some atheists have adopted the terms strong and weak atheism to clarify whether they consider their stance one of positive belief (strong atheism) or the mere absence of belief (weak atheism). There are also gnostic atheists. "Gnostic" is an english word meaning knowledge. A gnostic atheist knows that there is no god or supernatural of any kind and does not believe that there is any god or supernatural of any kind. (Introduced in The American Rationalist, Jan-Feb, 1994, by Paul Keller.) Many self-described atheists share common skeptical concerns regarding supernatural claims, citing a lack of empirical evidence for the existence of deities. Other rationales for atheism range from the philosophical to the social to the historical. Additionally, although atheists tend toward secular philosophies such as humanism, naturalism, and materialism, there is no one ideology or set of behaviors that all atheists adhere to. Although atheists are almost invariably assumed to be irreligious or non-spiritual in Western culture, this does not necessarily hold true for all atheists. Some religious and spiritual beliefs, such as several forms of Buddhism, have been described by outside observers as conforming to the broader, negative definition of atheism due to their lack of any participating deities. Atheism is also sometimes equated with antitheism (opposition to theism) or antireligion (opposition to religion), despite most atheists not holding such views.
