I forgot what kind of fallacy it is that relies on the complete refutation of an unrelated topic and then goes on to assume your own proposition is therefore somehow valid. Argument from ignorance? I don't feel like poring over the fallacy list to find it.

The obvious fallacy in the O/P (original post) of this thread is that there was no justification for atheism given. There was also no definition for atheism given. So let me start by providing the missing definitions and then we can go from there.
Theism is the belief in gods and angels and evil spirits. It is a specific form of metaphysics that is loaded with doctrine, dogma, and presumably revelation. Christian revelation has been transmitted by the apostles and evangelists of Jesus in the Greek New Testament, in Greek.
Muslim revelation has been transmitted by the scribes of Muhammad in the Quran.
Hindu revelation comes from several books notably the Gita's. And so forth. There are about a dozen major world religions.
In addition to these major religions, Philosophy contains the notion of the Philosophy God, an indistinct Being presumed to be all knowing, all powerful, all seeing, all present, immortal and infinite. Those are the characteristics that the various philosophers from Socrates to Leibniz have given for Him/Her/It. The notion of the Philosophy God is monotheist because there is no logical reason to assume there is more than one such God, even though in reality in the Universe outside of the study of metaphysics there very well may be a plurality of Gods, such as in Hinduism. The primary argument in favor of the existence of a Philosophy God are the various proofs of God from the Romantics (those who love God): First Cause, Prime Mover, Purposeful Designer, Artistic Artificer, etc.
Atheism assumes there is no God. This is a negative and as such cannot be proven. To prove a negative you would need to search every square inch of the entire Universe in order to be able to report there is no God or that God is dead. There are billions of galaxies in the Universe, and we have only send a few quick manned probes to our own Moon and unmanned probes to a few of our own relatively close planets. Ergo it is impossible to prove anything about atheism. Thus lurching onto the belief of atheism is no more rational than doing so with theism. Q.E.D.
Agnosticism on the other hand is perfectly valid as a viewpoint. Agnostics simply say "show me a sign and I will believe in a God." And in the meantime they suspend judgment one way or the other. Naturally theist religion condemns this viewpoint as lacking faith. I'm not sure that faith is a requirement for being rewarded in any of the various religions' Heavenly Kingdoms. Good works is normally the criterion for any reward, whether you have faith or not. Therefore whether you are an agnostic or a theist, you should strive for good works, such as those described in Matthew Chapter 25: to feed the hungry, to quench the thirsty, to clothe the naked, to shelter the homeless, to heal the sick, and to visit the imprisoned. Then you can expect a reward, even though your faith is weak or nonexistent.

Young does the best job of literally translating the Bible in his YLT version so I normally quote that one when I quote anything.
Atheism is a lie. Atheists are liars. Hell has a special place for liars in every religion. People view atheists with disdain for good reason. Q.E.D.
Now work within those specific definitions and refute my philosophy if you can.
