Disclaimer: These are my beliefs and/or best guesses. I submit that I do not believe them to be 100% factual. Nobody knows anything of the absolute beginning of all things. Anybody who claims they do is misinformed, or shortsighted (i.e. The big bang is not the beginning. What happened before that? What about before that?)
1. who the f*** created us?
I'm so ridiculously torn here. It is equally as believable and unbelievable for me to believe that everything happened by chance, or that everything happened because a deity made it happen.
If it was by chance.... holy s**t. Nobody should ever be depressed again. The fact that we exist shows our endless fortune. It is the epitome of good luck.
If it was set forth by a deity.... holy s**t. Where did this god come from? What about before that? He couldn't have always existed, right? If he did, what does that mean... 'always'? My mind cannot fathom that prospect. As humans, we understand beginning and end. We can't understand something without a beginning, or without an end, as we have never encountered it. Our laws state that something has to come from something else, and that everything has an end point. The same holds true for everything happening by chance.
Insane and incomprehensible, either way you look at it.
This is another question I can't begin to have an answer for. Personally, I believe that your purpose is what you make of it. I believe my purpose is to improve the world I live in while enjoying the ride.
3. what people think, i mean we see so many people during the day, ea of those people have a story.
This all depends on the topic. The field of Psychology has some pretty good answers for this.
4. we surround ourselves with a group of people, our inner circle, aka family, friends, but we never stop and realize that its not just us, theres a world full of people.
I wish more people would remember this. I think we'd all be a little nicer to each other if we could remember that others exist, and think about their daily struggles. We hide behind a veil of anonymity. The internet has made it worse than ever. We can say and do negative things to others without repercussion. If we ignore the possibility that others may see the world differently, we can just call them assholes and step on them, dismissing them as lesser beings out to hurt us. If we took the time to think about others, and try to understand their plight, I really believe we'd live in a better world.
5. we get so caught up with our lives that we never stop and enjoy what we have.
This is another thing that people should take some time to remember. We are so rich. All of us. It doesn't matter what you have, others who have had less have been happy with what they had.
6. what happens after you die, do you become energy and just float around? (i hope, i would be a peepin tom lol)
No idea. I mean, the body obviously decomposes and becomes a part of the Earth (or wherever you're laid to rest). Whether or not there's a secondary component (heaven, floating around, ghosts, whatever), unlikely, but possible.
