As a piece of reasoning, this post is just...embarrassing. It's basically one conclusory statement after another. It's chocked full of non-sequiturs.
Basically, he argues thusly: If there is not God, then life is meaningless. Therefore there is a God. There are several problems with this statement. First, the premise (that if there is no God, life is meaningless) is simply a non-sequitur. He does not explain WHY God is required to give life meaning, or WHY meaning can't be found in various other ways, he just CONCLUDES (without basis) that life is meaningless without God.
Life is NOT, in fact, meaningless without God. I do not believe in believe in God (as WLC uses the term) and yet my life is chocked full of meaning. Also, contrary to his assertion, I am not "terrorized" by the thought of death. I rather enjoy my life at the moment, but I also find the thought of a long, endless sleep to be quite...peaceful and liberating.
Not only is his premise flawed, but the conclusion he draws from it is a non sequitur even if his premise were true.
Even if life would be meaningless without God, it does not mean that God exists. Meaninglessness is a valid possibility. WLC's personal preference for God-based meaning doesn't cause God to spring into life to satisfy WLC's needs.

(also known as anecdotal fallacy)
conceptually valid perhaps, but not scientifically:
a) because it precludes science/knowledge. To say something is unknowable (i.e. 'no purpose') is anti-science.
b) meaninglessness has never been observed by science - everything is cause and effect.
The notion that existence is meaningless is essentially a superstition (belief in the supernatural) - it's outside the laws of nature in which everything has purpose/reason for existence - as defined by the law of cause and effect - which is the foundation of all science. Cause is reason, reason is purpose, purpose is meaningful...
I kept laughing out loud reading it so I had to read the whole thing out loud to my gf and other friends, kept us laughing / being irritated / saying "what!?" for some time. The overall conclusion is a word OP used a lot, absurd.
