Open Challenge: Evidence of a Young Earth

I like the role reversal, so why not give it a try.There are radioactive elements naturally occuring on the Earth today that have relatively short half lives (C-14 5,000 years I believe). Scientists claim that these elements are being constantly produced, e.g. C-14 is produced in the uppper atmosphere/ionosphere. However, it cannot be argued with any certainty that every radioactive atom with a short half life has been produced by these means. Therefore, without certainty, C-14 could be proof of a YE.

Again, just a little role reversal (see first message). I had a hard time writing my argument, thinking the same things you just wrote. Besides, you would think that proponents of an old earth (4.5e9 yr) could at least come up with better arguments that YEC's.Take a deep breath, just playing Devil's (err Christianity's) advocate.
