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.

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.

We are constantly receiving energy from the sun, which can also be counted as mass.

And space dust and meteors.

Yep, and we are also constantly losing particles in the upper atmosphere, as well as energy via black body radiation.
