I do watch Family Guy, though not much recently (I've watched them too many times.)
I didn't think of family guy when I wrote this.

To the contrary, you not-that-deep-thinker.

Rot i n the ground when you die? That seems awfully negative and I hope you don't tell your children that. Sagan expressed belief in some form of god as he was agnostic a nd his wife is publishing a book on some of the notes and conversatyions he had about god. Im not a deep thinker because im against you saying death is rotting in the ground? you judge by that your that pathetic?

Clearly you're a complete moron. If you know there won't be anything after this life, you will take advantage of what is logically your only life. He was an agnostic in the same sense that I was an agnostic: a de facto atheist. You're so ignorant and stupid that I should poo
An agnostic DOESN'T BELIEVE IN GOD!
Ahahahahahaha do ... ( 3 months ago by Reido2828)
Ahahahahahaha do research and your the ignorant one son a true man and intelligent person won't get hostile like you and use moronic words but would rather defend his points decently which is what sagan always did. PLUS!!!! an agnostic neither believes nor disbelievers because simply they cannot prove it. Sagan said quote for quote I can't see god so I am an agnostic but noone knows his opinions on the subject in the later years of his life. Im not a christian nor religious but i know we wontrot
Maybe you'll rot in ... ( 3 months ago by Reido2828)
Maybe you'll rot in the ground because your loved ones won't be decent to you and give you cremation because your an ass. Go do some research on all forms of religion and faith and paranormal don't be so fixed mineded because its possible to believe in evolution and believe in a soul or eternal life. I hope you don't teach your kids that. maybe open up your mind a bit and pay more attention close attention to the things that happen and if nothing does for you then change from being A-hole
Since the agnostic ... ( 3 months ago by Dan14159)
Since the agnostic neither believes in god nor disbelieves, he doesn't believe.
How much simpler can this get? Do you even have a brain?
You are deluded. Very intelligent people don't need to be so proper. That's only the stereotype.
It's confirmed that I'm in the 4th standard deviation.
One of my friends, ... ( 3 months ago by Dan14159)
One of my friends, a translator, programmer, and biologist is very proper. He is the opposite of a teenager. He's at the 3rd + standard deviation. That supports your idea. However, the most brilliant friend I have ever had the luck to meet is a chemical engineer and an astrophysicist who I'm going to be working with. His IQ is in the 6th standard deviation-- to him, both me and my other friend are complete imbeciles.
Here's the thing: ... ( 3 months ago by Dan14159)
Here's the thing: he has an enormous vocabulary, but he doesn't speak as properly as my other friend. While he uses lots of unknown words, he has a similar sort of immaturity as I do. Your idea has been thrown out the window, unless I'm wrong, which I'm not.
I won't be cremated ... ( 3 months ago by Dan14159)
I won't be cremated. Along with my two other friends, my body will be used for medical research.
I forgot to mention, my supergenius friend is also a part-time medical researcher.

What does this have to do with anything? Imagination is what I was hinting at and whos to say we don't have a soul huh why do we rot in the ground at death

I'm showing you that saying poo doesn't make me retarded.

It is quite interesting that we have proof of artificial selection exist. We visit our grocery stores and see the produce of artificial selection, where the produce are very different from the original wild variety. However, there are people who can not accept natural selection a process that is more integrated that artificial selection.
