Hello, it looks like you have made it here because you have no understanding of the basic theory of evolution and wish for it to be explained to you in an incredibly simple way that the stupidest of humans could understand.
If you agreed with what I have just said you are either 1.So incompetenct that a thirteen year old with an average IQ has a greater understanding of biology that you OR 2.So young that you lack an ability to comprehend what I am saying and thus lack understanding of evolution and then wish for it to be explained to you in an incredibly simple format.
Now assuming you fill the criteria for number one in the above sentence I will guess that your a creationist , if you match the criteria for number two above I will not even bother explaining anything to you.
Even if you are not a creationist this will still satisfy your needs. (Also you are in a minorty group.)
So if you've gotten to this point you probably know what evolution is so I shall not bother explaining that to you.
You probably have a misunderstanding of what it is, so Ihave taken it upon myself to address all of the common misunderstandings of evolution in the form of arguments against evolution.
The first one I am about to present is probably one of the ones I have heard the most on the internet.
"Life can't come from non life."
If you have this as a question then you have a MAJOR misinterpretation about evoltuion
First of all this is not even an argument against evolution, as evolution is the study of the diversifying of species after the first cell had formed.
Even if this was a cohernet argument it still would not hold up.
What this argument refers to is abiogeneis and trying to state that it does not make sensewithout a shred of evidence against it, in fact there is a lot of evidence for abiogeneis, for example we heve observed simple self replicating cells coming from a tar like material, the only information that we don't have about abiogenesisis what conditions it can happen in, it can happen in tar but we don't know if it could have happened in the conditions of early earth.
