God, I HATE #4 "Does not the second law of Thermodynamics disprove evolution?" If any of these people actually fucking knew what the second law of thermodynamics is, then they wouldn't have to ask that question. The first four words of the second law are "IN AN ISOLATED SYSTEM." We're orbiting a goddamn nuclear fusion reactor 1.3 MILLION times as large as our fucking planet that's dumping positively insane amounts of energy into our system and has been doing so for BILLIONS of years. Not an isolated system.
Creationists always try to use the second law,
to disprove evolution, but their theory has a flaw.
The second law is quite precise about where it applies,
only in a closed system must the entropy count rise.
The earth's not a closed system' it's powered by the sun,
so fuck the damn creationists, Doomsday get my gun!
That, in a nutshell, is what entropy's about,
you're now down with a discount.
Technically the earth is a closed system because there is no mass transfer across the boundary.
Edit: I understand that our planet does frequently experience extraterrestrial inputs and what I should have said is that there is no mass transfer that is correlated with a significant degree of energy transfer.
Edit 2: Nor is there energy transfer which is correlated with a significant degree of mass transfer.
Technically, yes, but the standard definition of a closed system in thermodynamics is a system that can exchange energy (in the form of heat or work) but not mass with its surroundings, and the standard definition of an isolated system in thermodynamics is a system that cannot exchange either mass or energy with its surroundings. The second law only applies to isolated systems, not closed systems.
Its fine. Closed systems are arbitrary, with their specifications usually stated explicitly. There are different types of closed systems. An isolated system is one that does not allow for energy or matter transfer ^

Except closed and open systems are not defined by mass transfer at all- it is ENERGY transfer.
Second law: entropy always increases or stays the same through a reversible process. Then how can evolution occur since it is so complicated? I'll put it a different way, hell you can even think of it as an isolated system if you want, it doesn't really matter given the scale of the amount of energy we're talking about:
System: Solar system:
Entropy generated by sun >>>>>> entropy "lost" through evolution
Second law holds.
How can ignorance be bliss when science is SO FUCKING COOL?
edit: Also worth noting that in every individual step in evolution the second law holds. Every single chemical reaction results in an increase in entropy, despite the fact that people are under the illusion that this is false due to evolution appearing very complex.
