If I see dead stuff (organic)
And me being 100% reasonably
I’m going have to say
Something die there
Something once live
You don’t just find a dinosaur bone in your backyard
After I eat a chicken
There left over bones
Two things. First, that's not how "science" and/or the the scientific method works.
Second, what you have here is a false dichotomy. There's not only two answers here. There are many reasons why organic matter was found there. Your first premise is what makes your argument fail. You assume that the organic matter originated from there without having any further investigation.
Your example about the bones does nothing to support your argument because the conclusion is different. Here's the breakdown.
Argument: Finding dinosaur bones in your back yard, you concluded that a dinosaur died there.
Evidence: after you eat a chicken, there are bones left .
It fails because the evidence only shows that those animals that have bones may leave their bones behind when they died. Nothing indicating that a dinosaur once roamed and died in your back yard. There are other possibilities for the bones being there. Ex: it was brought there by some other means, whether by a living force or nonliving force, such as gravity. Plate tectonics moved it there. Glaciers brought it there from somewhere else. It's similar to those arguments from YEC claiming fossils of marine animals that were found up in the mountains as proof of a recent global flood because the mountains were under water at the time.
