The age of the earth is accurately represented by Christian Scripture (approximately 6000 years).

"This can happen very quickly, not taking millions of years to do." First to start, what exactly is kind compared the known taxonomic ranks. Second, how do you overcome the small gene pool problem of a single breeding pair. Third what happens is a pair gets sick, it is killed (eaten), or is simply injured and does not mate. "The saltiness of the ocean." The oceans are salty because as rain falls it hits the ground, picks up salt and sediment, goes into the oceans, as it evaporates then it leaves salt/sediment behind. Oceans/seas with high rates of evaporation have high salinity. Over time, the salt content tends to stablize from fresh water sources (rivers, etc.) [1] "The decaying magnetic field limits earth's age to less than billions." This argument was proposed by Barnes[2] who looked at a set of data for the last 150 years, found that they had a steady exponential decrease backwards and then traced that same decrease backwards (as an increase) and found that in less than 10, 000 years the magnetic field would be so large that life would not be able to survive. The simplest way to debunk that is to note that the measurements were only of the dipole component and if the total energy is measured then his correlation disappears. Note as well that the fit was non-weighted, a horrible practice on combining data from different experiments with known variations in experimental errors. "The erosion rate of the continents is such that they would erode to sea level in less than 14,000,000 years, destroying all old fossils." Interestingly enough, what age of the earth does this argument actually advocate? This calculation was exceedingly simple, it simply took the mass of rock above sea level and divided it by the sediment deposit in the ocean[3]. This calculation ignores even basic processes of the geological sciences such as mantle-crust recycling[4] and Sediment recycling by tectonic uplift [5]. In short, that simply means the sediment and exposed rocks move around (recycle), you can not just assume it was always the same and move back, rocks for example can be exposed to erosion which had been previously heavily eroded and then went under the crust (tectonic recycling). "So why are we still finding oil that supposedly has been underground for millions of years?" Oil moves around in the earth, more interesting is that the rate of movement is so slow that if the earth was just a few thousand years old there would be no significant movement at all from the point of origin (1-5 km down) [5]. That points to a few obvious problems (oil would tend to always be at the origin depth). "Why did the oldest desert originate right after the time that creationists believe the flood to have happened?" The Sarah desert is in fact fairly young and its history is well known. Less than 10 000 years ago it was wet and suitable for grazing in locations, more than 10, 000 years ago there were lakes and streams there and it was grassland[6]. The earth has has a complex geological history it would not be expected to have the same environment untouched for the life time of the earth. "Go back a couple hundred million and the moon would be right above the earth." The distance from the earth to the moon is approximately 400, 000 km. If the orbit changed by 1 cm every year for 100 million years that would only be a change of 10^-2 (cm to meter) *10^8 (one hundred million) *10^-3 (m to km) which is 10^3 (a thousand) km. It would not be right on top of the earth. Note the rate of change has steadily increased so in the past it was a lot lower[7]. Note that the developed models for the earth-moon tidal system show an age in agreement with the known radio-metric age of the earth[8] To end on a key point, note how many young earth arguments have been made (in non-peer reviewed citations) but how many give a consistent calculated age of the earth. If they are actual valid dating methods they all should agree with the correct age and this age should be consistently refined as the methods are advanced. This is however not seen. However all the peer reviewed models all will end up with the same consistent age as they have to as they are all based on the same fundamental scientific principles, it is a coherent system.
