The actual possibility of One strand of DNA being created is 1 to 10 to the 86th power that is: 1/100000000000000000000000000000000000000000000000000000000000000000000000000000000000000
And, That is for only one strand.
Imagine a human that would be like 1 to 10 to the 34625683456827346587346531465 8163487561875461834568176345
Thus beliving science takes a lot more faith.
Another example is if you smash, Lets say a clock, or pocket-watch, and then shake it around in a bag for about 1000 billion years, Will you end up with a clock?
I think not.
Do you even know anything about genetics? Did you bother to look anything up or did you just pull a random number out of your gullible ass?
Genetic material is made up out of nucleotides, these molecules are represented by the letters A, T, C/U and G and those letters are the alphabet of genes. These molecules are somewhat more complex than the other molecules floating around in the universe, so your first question probably is where they came from.
Answer: These molecules are formed in early-earth conditions. (
http://en.wikipedia.org/wiki/Miller-Urey_experiment)
The first notable thing about nucleotides is that they can link together to form a long chain, which is what you'd get when you tear a stereotype DNA molecule in half. Another notable thing about nucleotides is that they come in pairs: A attracts T and C or U attracts G, which means that next to your chain of nucleotides another chain forms, which is exactly opposite to the first chain. These chains can be separated and a new chain will form next to the second chain, thus the third chain will be a copy of the original chain. Result: these molecules replicate on their own.
A chain isn't always copied correctly, because of UV-rays, radiation, heath,
god, ... This means that we get different kinds of chains, some are longer, some are shorter, some are folded up, some aren't, this means that some chains are easier to replicate than others, which means that they'll replicate more and become more abundant. The fittest chains survive and reproduce.
Next up: proteins. Proteins consist of a chain of building blocks which are called amino-acids. These amino-acids have 2 spots to link to other amino-acids and one spot which has a specific part of a molecule, which performs a certain function. Some of these amino-acids bind with small nucleotide chains, the nucleotide part of this molecule is attracted to a longer chain and binds to a specific spot (an amino acid bound to ATA would be attracted to the TAT-part of a longer molecule), the same happens for other amino-acids. The result: a chain of amino-acids is formed next to a chain of genetic material. Genetic material has created a protein.
Now that amino-acids and nucleotides are working together they can begin to form bigger structures: a cell. Genetic material which creates a protein-shield around itself is better protected against UV-rays and other nasty stuff, and has more chance of survival, thus there will be more genetic material with a shield around it. Cells evolve other structures similarly.
Some of these cells mutate in such a way that they stick to one-another, which means that blobs of cells emerge. These blobs are bigger than smaller cells and can't be eaten by small cells, thus they have more chance of survival and reproduction. Some of these cells specialize: some make energy, some move, ...
As these blobs get bigger and bigger, complex organisms begin to emerge.
This is where macro-evolution begins: There's a large group of organisms of the same species with slight variations in genetic material. These slight variations make them different, they have different abilities and disabilities. Suppose a new toxic substance is released into their environment, some of the organisms will die instantly, and some are a bit resistant to the toxin. The resistant organisms survive and have more chance of reproduction. They reproduce and their offspring is more resistant to the toxin. This happens for several generations until the organism is completely immune to the toxin. The organism has evolved immunity. This happens for other properties too: Some of them evolve organs that are sensitive to light and so they can see their predators, thus they're able to avoid them, thus they reproduce and more organisms grow eyes because it gives them an advantage over organisms without eyes.
Do this again and again and again for countless generations and you end up with the animals we have today. Genetic material wasn't randomly smashed together just once to form an animal, it happened in stages, with the randomness providing both good and bad properties and the environment filtering out the bad properties.
There's lots of proof of evolution too (as opposed to all the mumbo jumbo in the bible):
- Homology: all animals share common features: 4 limbs, 2 eyes, a nose, a stomach, a digestive track, lungs, etc.
- Embryology: embryos go through their evolutionary background as they develop. For example: human embryos have gills at a certain point.
- Observation: both micro- and macro-evolution have been observed.
- Fossils: fossils of extinct species show the steps between different types of animals, for example, reptiles growing feathers and becoming birds or fish growing legs.
- ...
TL;DR: Don't bother to reply if you didn't read it all.
