Are atheism religious beliefs protected by the Constitution? Let's discuss the arguments and definitions of atheism. We will also consider whether atheism qualifies as a religion or a religious belief in the Constitution. Atheism is a philosophical belief that rejects any form of deity.
Arguments in favor of atheism
Atheism refers to a philosophy that rejects belief in gods. There are several forms of atheism that are common. They all reject the idea there is a Supreme One. These religions include Hindu, African, and classical Greek religions. A few atheists have even rejected the idea altogether of a divine being.
Atheism is supported by the lack of evidence that gods exist. The belief that gods exist is founded on the belief in a supreme being, which is not subject to nature's laws. It is the believer's responsibility to prove the existence of an inexplicable entity.

Epicurus and other philosophers developed materialistic theories that challenged religious belief. While he believed in the existence of gods, he asserted that they were uninterested and impersonal. Ataraxia was a philosophy that the Epicureans tried to attain.
Definition of atheism: A religion
Atheists believe there is no God. They don't necessarily reject all religions. Many of them practice their faith. Some of them are even devoted members of theistic groups. Atheism must be understood as a religion and not a philosophic 'no god'.
There are many definitions of "atheist" and each has its own pros/cons. According to Encyclopedia of Philosophy, an "atheist" is someone who rejects the existence of God. Others believe God doesn't exist and religions are false.
This second definition is too broad. The definition of "atheism," however, is too broad. Fideist believers, for instance, believe God exists, even though there is a low chance of it. They believe in God, because they need higher power to understand the world. Atheism fails to recognize them.

Is the Constitution able to protect atheist religions?
The First Amendment protects everyone's rights to worship God. However, the establishment clause of the Constitution prohibits governments from favoring or establishing a specific religion. This clause also prevents discrimination towards atheists, a minority in America.
