Young-earth "proof" #24: Given the rate of salt influx to the oceans, they should be much saltier than they are if the earth were billions of years old.

Dr. Hovind is assuming that salt cannot be removed from the oceans. The more sophisticated creationists, such as Melvin Cook, know better than to make that assumption. Here's what Cook had to say:

The validity of the application of total salt in the ocean in the determination of age turned out to have a very simple answer in the fact shown by Goldschmidt (1954) that it is in steady state and therefore useless as a means of determining the age of the oceans. [Cook, 1966, p.73]

(Dalrymple, 1984, pp.115-116)

Thus, salt is being removed from the oceans as quickly as it is being added by the world's rivers. Consequently, no age can be calculated, save a minimum age based upon an assumption of initial salt content. There is no comfort here for the young-earth creationist.

For an alternative "creation" view-point, see this post, when modern Science and Genesis, can be reconciled and harmonized... the truth speaks for itself.

They said it couldn't be done, but here it is, thanks to modern science and praise to God.
    "The various attempts to join together the biblical account of creation and evolution are not supportable by the various gap theories because the order of creation is in direct opposition to the views of modern science (e.g., the creation of trees before light.)"

Yes, finally, trees exactly as described in Genesis, before, and without sunlight. And no, it's not another lame hoax. (Short) and (Long). See, Prototaxites, Fossilized "Fruiting Fungi," 'Tree'.

Besides science
discovering this fossilized, non-photosynthetic, fruiting "tree," Genesis does not mention flowers (Angiosperms), which supports Old Earth Evolution. How odd for "mere mythology".
