Can someone explain to me the scientific theory of creation?

Question

All I really know about it is something about dust and particles...and somehow that formed everything? I probably sound really stupid, because I honestly don't know a lot about the scientific theory of how we all came to be, but from what I know, I don't fully believe it. What I know about the human body seems WAY too complex to have been made out of dust. So if anybody could explain it to me, that'd be very helpful!

Thanks,

It seems like you're looking for a lot of information in a very small space.  There is no single scientific theory of origin. The information presented here draws on many different theories from several different branches of science.  I'm not sure I can deliver what you're looking for in this forum, but here goes...

About 13.7 billion years ago, all matter and energy in the universe was compressed into an infinitely small space. For some reason (we don't know why, but there are some pretty good educated guesses), all of this matter and energy began to expand at the speed of light. This evert is typically called the Big Bang. The universe is still expanding at the same speed.

Over time, some of the matter released in the Big Bang started to congregate together in balls, under the force of gravity. In some cases, so much matter collected together that pressure on the inside of the ball was sufficient to cause nuclear fusion. The process of fusion made it possible for heavier elements to exist.

One of these big fusion balls happened to be our Sun, which is slowly sucking in a much smaller ball (mostly made of iron) which we call Earth. Earth finished forming under gravity around 4.5 billion years ago.  It's had a pretty rough history since then, alternately freezing over or burning over, which a bunch of other crazy stuff in between.  One of the crazy things that happened on Earth was the formation of a self-replicating molecule, that is, a chemical structure that can make copies of itself. This happened about 3.7 billion years ago.

The copies that these self-replicators made were not perfect. Occassionally, they would make a mistake, and the copy would be a bit different. These differences would either make the copy better at making more copies or worse at making more copies. Over time, copies that had the "better" differences became much more common and spawned even better versions when they made copies.

One of the things that tended to make self-replicators better at copying themselves was complexity.  Complex chemicals survived more easily and made better copies than simple ones.  Over time, more complex chemicals became much more common. As these structures became more complex, they were able to incorporate extra structures that increased the overall chance of self-replication.  One of the most important structures that developed was a membrane around the structure that kept good chemicals in and kept everything else out. The formation of these membranes marked the very first cells on Earth, and the first things that we consider "life". This happened about 3 billion years ago.

Of course, not every cell evolved in the same way. Some "family" lines developed the ability to use sunlight for energy.  Some lines simply improved on the single-cell model, leading to all the various bacteria in the world. One of the big developments is that some cells developed the ability to work together. These were the first multicellular organisms. Their family lines led to most of the life on Earth that you can see without a microscope. This happened about 1 billion years ago.

The development of multicellularism gave way to another important development: specialization.  Since multiple cells were working together, not every cell had to be an exact copy.  Some cells could be specialized to be more efficient at a particular job. This led to the formation of specialized tissues and anatomical structures, thus opening the door for all of the various forms of life on Earth. These first animals existed about 600 million years ago.

Over the intervening time, all of these various family lines split and changed and split and changed and split and changed until they produced the the animals that we see today.  Humans are one of those animals, the result of the same processes that formed all other life on Earth.  This process is still occuring, with the ancestral lines of all organisms continuously splitting and changing with each generation.

Hope that helps.  Feel free to email me if you have any questions.

You have some good answers here.   It sounds like you don't believe in evolution.   A lot of people do not, but I do.  The concept of how life on earth began and changed is pretty complicated and requires belief or trust in some theories.   Life could have begun from certain atoms like carbon, hydrogen, nitrogen and oxygen combining due to forces involving heat or electric energy.  Once [primitive life forms occurred, they could have gradually evolved into more complex forms by the principles of evolution, which involve mutation, and natural selection.   These two things have been demonstrated to occur here on earth frequently.  Read up on mutation and natural selection, and it might help.

Err, which theory are you talking about? The theory of creation purported in the Bible? Because that's the theory that claims we were created from dust... the scientific theory of the origin of life claims otherwise - it suggests that the first lifeforms were based on RNA molecules, and the subsequent process of increasing complexity was shaped by evolution.

Answer 4

Okay, if the creation story is true, and there is alot of reported evidence for creation by the way, then the creation of the human body from dust would be way less complex than creating planets and other creatures out of nothing.

Answer 5

Let's see - Big Bang (a massive release of energy), nucleogensesis (creating matter out of energy), gravity drawing matter into massive balls of gas, gas coalescing until nuclear fusion ignites, stars creating new elements in the fire of their furnaces, stars explode (at the end of their life) releasing all the new elements into the cosmos, new stars coalesce from the dust and debris, gravity takes over (again) and fires up the nulcer fission reaction anew in second generation stars, planets form around them carrying the atoms necessary for life, planets cool, water forms on some planets creating the breeding ground for the formation of simple hydrocarbons and amino acids, sparks fly, simple cells come along and (over millions and billions of years) evolve into more complex entities.  Then your mommy and daddy fell in love and voila, there you are.

As for being too complex, consider this, if complexity requires a creator, then the creator must be even more complex so logic dictates that the complex creator must have had an even more complex creator.  Ergo, complexity is not a reason for positing a designer - not unless you are willing to admit to an infinite string of gods, supergods, ubergods and supragods.
