You might object that professionals excavate to acquire knowledge, not money. Moreover, ancient artifacts are part of our global cultural heritage, which should be available for all to appreciate, not sold to the highest bidder. I agree. Sell nothing that has unique artistic merit or scientific value. But, you might reply，everything that comes our of the ground has scientific value. Here we part company. Theoretically, you may be correct in claiming that every artifact has potential sciencific value. Practically, you are wrong.
