I am an agnostic atheist, if that counts. I am convinced of the non-existence of all of the culturally-defined and anthropomorphized gods of which I am aware, such as the Judeo-Christian God, Allah, and various pantheons such as Greek/Roman, Norse, Egyptian, Hindu, Chinese and Native American gods (I cannot rule out the possibility that other kinds of gods exist).

1a A Being perfect in power, wisdom and goodness could not create imperfect creatures, put them into a situation where they would be forced to suffer needlessly, or fail to alleviate such suffering. I observe imperfect creatures suffering from things such as genetic defects, diseases, pests, and natural disasters that are not attributable to mankind's alleged sins. It would be possible for an omnipotent Being to alleviate this suffering, but it continues unabated. Therefore a Being that is omnipotent, omniscient, and omni-benevolent does not exist.
1b It is impossible for an infinite Mind to exist because information transfer is inherently limited to the speed of light, therefore it could not communicate with itself. It is impossible for an incorporeal Mind to exist since the data acquisition, storage, retrieval, and processing necessary for intelligent thought requires some kind of structure.
2 No one has proposed a credible origin or modus operandi for any supernatural being or powers, or explained why it would require or desire human worship, or provided evidence that any aspect of reality has ever been controlled by a supernatural force.
I do not believe that an immortal soul exists because drugs, disease and/or trauma to specific areas of the brain can impair consciousness, memory, volition, personality, and various mental abilities. If "I" can be altered even slightly by physical damage to my brain, then logically "I" do not exist independently of my brain. When an Alzheimer's patient dies, does his soul magically regain all of the memories and mental acuity he once had? If so, how and where are these memories kept and why could his soul not access them while he was alive?
If there is no immortal soul, there can be no afterlife, much as we might wish to be reunited with loved ones in Paradise, and rejoice over the retribution meted out to those we hated.
