Answer
Because Fool's Gold (iron pyrite) looks like gold, but it is not real gold. It fools the finder into thinking he has found real gold. A fool will persist in thinking it is gold even when it is proven that it is not real gold.

On the lighter side:
Some poor prospector thought he had gold, due to the shiny gold appearance of the pyrite he discovered. When he took it to the assay office, the assayer said "You have been fooled by the gold like appearance of this mineral, which is actually called 'pyrite'." Henceforth, the assayer ridiculed hundreds of subsequent prospectors with the exclamation of "Fool's Gold!" sometimes in jest, and sometimes in earnest, but always in vague reference to the suspected intelligence of its target. Pyrite thus became the only mineral to be associated with fools and the perpetration of foolishness.
Gold is a heavy ductile metal and gold is an Element. Fools gold is actually Iron Pyrite and is brittle and light compared to gold. Gold has a specific gravity around 19 while fools gold (iron pyrite) has a specific gravity of 4.95 to 5.10. Fools gold is harder than gold. The hardness of Fools gold is 6 to 6.5 while Gold is softer and has a hardness of 2.5 on the Moh's scale of hardness. When hammered gold will flatten while other yellow minerals break Fools Gold (Iron Pyrite) is a sulfide of iron,with a metallic appearance and occurs either as distinct cubical crystals or in massive crystalline forms.Pyrite is slightly harder than steel and cannot be scratched with a knife while gold is much softer than steel and can easily be scratched with a knife. Pyrite emits sulfur when heated...gold does not. There are many differences between Fools Gold and Gold, that is why "fools gold" got its name.
There two other names for pyrite. It is often called "fools gold"because it looks rather like gold. Its scientific name is iron disulfide.
hit it with a hammer: if it shatters its fools gold, if it flattens it is probably gold.
chalcopyrite is called fools gold because it's lustre looks like gold!
Fools gold is commonly known as Iron Pyrite which is Iron Disulfide - FeS2.
The mineral pyrite is fool's gold.

Fools Gold is actually 'Iron Pyrites' , sometimes just called 'pyrities'. Is it crystals of Iron sulphide. The chemical formul;a is FeS2 ( Iron(II)disulphide). Its appearance is slightly angular crystalline substance. The colour of fools gold is a slightly cooler yellow to natural gold.

real gold does not sing it sinks and so does fools gold.
No, fools gold or iron pyrites is less dense than gold.
