You know what? I'm just trying to ask a simple question and I know someone will say that they have already answered it or I'll have some asshole atheist use sarcasm towards me to think they are better than I am.
Settle down. Getting angry isn't going to answer your question. I haven't responded to you with sarcasm, or mocked you, and yet you've completely ignored my posts after I called your attempt to prove god a "fool's errand."
How could anything just happen by itself?
All sorts of things happen by themselves. Stars form spontaneously. Snowflakes form spontaneously.
I want to know if the universe has always been here, how? I'm not saying it hasn't and I'm not going against science.
The problem is that there doesn't appear to
be an answer to your question. We know with a reasonable degree of certainty the state of the Universe from a tiny fraction of a second after the beginning of the expansion onward. But time
ends at T=0. Again, when you ask "what caused the Universe?" you're asking "what is North of the North Pole?" It's an impossible question without an answer, as we currently understand the Universe.
In my opinion atheists believe that this is the cycle of our universe and existence:
NOTHING BUT SPACE.......EARTH AND LIFE ON IT.......HEAT-DEATH WHICH DESTROYS EVERYTHING ON EARTH........NO LIFE JUST SPACE
Your opinion is incorrect.
The Big Bang does not propose any such thing as "nothing but space." Here's something mroe accurately describing the timeline:
(The Universe exists in an incredibly small and dense form. Our mathematics cannot describe it at this point, because matter would have existed in a form we do not yet understand at that level of heat and density.)
->
(Beginning at T=0, the Universe expands at an exponential rate. This is not a chemical explosion like we're used to, but rather the dimensions of length, width, and height are expanding. Becasue the volume of the Unvierse increases, the density decreases, and things start to cool down.)
->
(Something we would recognize as matter begins to form from the state it was in previously. All matter in the Universe exists as a quark/gluon plasma - basically it's composed of the particles that make up protons, neutrons, etc, and they're still so hot and dense that they haven't formed into normal subatomic particles yet.)
->
(As the expansion continues, the Universe cools down more from the ever-decreasing density. The epansion slows down. The quark/gluon plasma starts to coalesce into matter and antimatter - matter "wins" becasue there happen to be more quarks than antiquarks. The antimatter that
does form is quickly annihilated into gamma rays by contact with equal amounts of regular matter until basically only normal matter remains. At this point, roughly 90% of the Universe exists as Hydrogen nuclei, with the rest mainly being composed of Helium. Electrons still cannot bond to the nuclei as it is still too hot. We are now at T=10^-16; in other words, we are now at 0.0000000000000001 seconds past the beginning of the expansion.)
->
(While the Universe continues to expand at something closer to the rate we see today, all of that Hydrogen starts to congregate around the most dense areas. After around 400,000 years or so, gravitational attraction forces the Hydrogen into such a small volume that the density generates enough heat to initiate nuclear fusion. The first stars are born, and boy are they gigantic.)
->
(After a long period of time, the first stars begin to consume all of their nuclear fuel. Basically, fusion creates heavier atoms out of two or more lighter atoms. Eventually the process reaches a point where the star becomes unstable, the gravitational attraction that holds the explosive force of all of the fusion finally loses out, and the star explodes in a supernova. This is literally where all of the heavy elements come from, including everything you and I and the Earth are made of - leftovers from exploding stars. Pretty cool, huh?)
->
(The stellar life cycle repeats. Eventually the leavings of several stars in a cluster can congregate into a new stellar nebula, where a new star is born. becasue of the presence of heavy elements this time, solar systems compelte with planets can be formed. One such system contains Earth. Icy comets, since water is the most prevalent molecule in the Universe after H2, deliver water to the surface of the Earth.)
->
(At some point life forms on Earth. It may be abiogenesis, where non-living organic chemicals spontaneously combine to form the first imperfectly self-replicating molecule, like RNA. It may be space aliens, or a microbe from a comet, or god. The honest answer is we don't know how life got here, we just know that it wasn't here, and then it was, in the form of a single-celled lifeform.)
->
(The process of imperfect replication and natural selection take over, creating diversity among the new lifeforms. After several million years, multicellular life forms, and we begin to see some of the variety of life that we can observe today. This is what we call evolution.)
->
(After a few million years of evolution progressing, the first of what we would call human beings appear. A few scant thousand years later, I'm typing a response to you over a computer network we call the Internet.)
There is no "creation from nothingness" in the model currently held by scientists. Does any of this help?
