Welcome aboard. Asking questions is a good idea at any time (why do you think I am "nosy" eh? )
........Do you agree with the creationists that evolution is a "Theorey"(sic)
Funny question. Since it is possible to completely agree and completely disagree.

Fact and theory
It explains that not only is evolution a fact but that it is something much more powerful and important than a fact it is a full blown
theory. Theories are very important indeed.
That is why I can agree with them but they usually put "only" in front of 'a theory'. A theory isn't a "only". If it was "only" a fact that would be a lesser thing.
possibillity that there may be some other explanation on how species appear not neccesarilly involving miracles from god??.
Science always leaves the door open. It is tentative. However, there is so much evidence for the theory of evolution (the ToE) that the door is only just a little ajar.
Are there any human remains of around 10,000 years old?.....sorry if this is a dumb question....
There are human remains going back about 500,000 years. If you go as far back as that they are not exactly like a modern human. They are however, still classed as Homo sapiens but a subspecies.

I think your questions are jumping into some details a bit too quickly.
Before worrying about the details of the theory of evolution you should just worry about some over all facts. Which ones are important depends on which of the many different "creationist" views one is discussing.
First are the more extreme full out Biblical literalists that figure the earth is only 6,000 years old. You second question suggests that you are interested in discussing that.
The dates as background are important so I suggest you browse some of the dates and dating forum.
