I'm not.

Okay, it seems to me that you have claimed three things:
1) the set of things which exist has exactly the same members as the set of things with properties
2) to say in 2010 "Lincoln exists" is to utter a true statement because Lincoln has properties, or at least, Lincoln has the property of being dead
3) before the formation of the Earth, Lincoln did not exist.
Let's consider the case of sailors lost at sea, eaten by fish, their bodies digested and the fish dispersed to the four corners. In this case there is nothing we can point to and say "that's Ahab, he's dead", so it seems that there is nothing that could have the property of being dead. As a further example, there are porcelain coffee cups in this house and occasionally one gets broken, and that pisses my wife off, not because she's averse to coffee cups which have the property of being broken but because once broken they are no longer coffee cups. Just as Lincoln, once dead, is no longer Lincoln, the great orator, or whatever he was.
And, of course, dinosaurs. The vast majority of dinosaurs that lived have left no trace of their existence, thus all we can say about almost any dinosaur is "it was a dinosaur and it's dead". But according to you, that suffices for the existence of all dinosaurs, that is for a set whose only overall description is "were dinosaurs, are extinct".
Then there's the property of being a future president. This was true of Lincoln until he was inaugurated, which means that it was true long before the formation of the solar system, and this seems to commit you to the existence of Lincoln throughout the past.
So, as far as I can see, there are at least three ways of existing entailed by your position:
1) the existence of physical objects, with spacetime locations and with observable properties
2) the existence of causally inert unobservable abstract entities without location
3) the existence of category
1 objects that no longer have that existence but gain existence as parasites of type
2 objects.
