I'm sure most of you have seen this image on web mocking atheists for "believing" something that is obviously not true at all.
First atheists do not share a common set of ideology. The only thing common between all the atheists is that they lack belief in all gods but not necessarily in
other irrational ideas. We know the names of many man made gods. A list can be found
here. All these gods are false according to atheist point of view because they have no evidence of existence.
Second problem is, Atheism is not an ideology of any kind. It is actually lack of theist ideology. Does that mean, atheists believe in nothing? No. Atheists can adopt a range of different ideologies or views. Some of them can be logical and science based (as it should be) or illogical and purely based on emotional response. The former is called a rationalist, free thinker or a skeptic. I like these words. Particularly the word
Skeptic as you might have noticed already. ;)
The third problem i think is solved by the second image. It gives a rational and scientific answer to the allegation of believing in nothing. And the response is pretty good:
Although lack of belief in gods itself is not an ideology, it certainly forces a godless person to inquire scientific and rational answers.
A tiny bit of clarification: Although previously I've
argued the Universe COULD come from nothing, it must be remembered that scientists are still unable to prove one way or the other due to lack of experimental verification. It is also worth noting, the continuous effort of scientists to come up with a theory of quantum gravity. Our existing laws of physics breaks down in an extremly "zoomed in" space.
There are several theories (quantum fluctuation is one of them) for the origin of the universe. Among them
Membrane theory proposes the universe came from something (collision of branes). It is based on string theory. Other models such as
Ekpyrotic model based on cyclic theory.
Finally...the real meaning of atheism is...
I would recommend this
atheism.about.com link for anyone who is interested to have the correct concept of Atheism.
....And finally something for the religious folks too .
