How can we know how old fossils are?

Thnk about this, water they say causes decay of rocks, well how do we know that there weren't great floods that altered how old we think those rocks are? We also don't know for a fact the atmospheric conditions throuhgout history, so even though we can determine how rocks age in the present in our lifetime, we can know that something turns into something over 10 years persea, how can we know it changed to this degree over millions and millions of years not knowing the atmospher? Also if rain causes rock decay and water does, then that alters how old we think it is, in another words, if the water makes it older than it isn't really older. Does this make you think maybe science isn't all that accurate and those supposed evolutionary bones may not be old at all but different creatures just popping up around the same time? How can geology explain this?
Does rock decay and weathering disprove rock dating and other forms b/c it's decaying from atmosphere and not natural and how can we know which is which?

Google the following:
-Geology
-Radiometric dating
-Fossilization
-Stupid questions about the above three.

Ok but even radioactive decay, can you honestly explain that? If we don't know for sure the atmospheric conditions could that of affected the process of aging for the rocks? different climates and such, if not just let me know, I'm not a fucking geologist, just very curious.

No, climate conditions don't affect radioactive rates of decay. An isotope in the Sahara will decay at the same rate as the same isotope in Antarctica. Or on Mars.
If you're all that curious, try searching the web.

Ok but do climate conditions or atmospheric conditions affect a rock changing to a limestone, or like bill nye said 'its a fact that after 10 years it turns into formika", but would it be a fact during the Jurassic period?

At work.
Uhm... 'Radioactive decay'?
You know that sort of thing's pretty much untouched by little things like 'Weather'.
What, with it being all 'Atomic' and stuff.
