No one reads that sentence in context. Here is the next sentence

10 Is there any thing whereof it may be said, See, this is new? it hath been already of old time, which was before us.

Which is simply not true no matter how you look at it. Every idea still had someone think of it first and all but a tiny fraction of our technology is pretty freaken new. The whole poem is just a whiny rant by a person with an insufferable large ego.
