The Christmas tree is not that old at all. It comes from Germany. At most it can be dated back 4 centurions. It was also known as the 'Yule tree', and it associated with the god Odin. Heathen sacrifices, many bloody ones, feasting and a pagan temple are all connected to this.
Some people see a warning to Israel against decorated trees found in Jeremiah
3 For the customs of the peoples are worthless;
they cut a tree out of the forest,
and a craftsman shapes it with his chisel.
4 They adorn it with silver and gold; they fasten it with hammer and nails so it will not totter.
The prohibition against trees is actually shaping it and adorning it. The shape or carving goes back to the 10 commandments.
Exodus 20:4 You shall not make for yourself a carved imageany likeness
of anything that
is in heaven above, or that
is in the earth beneath, or that
is in the water under the earth;
So it is the cutting of the tree and carving/shaping it. This is a carved image which is forbidden. Then taking this carved image and adorning it. All a very specific and detailed description of creating a graven image/idol and decorating it to honor it.
A Christmas tree is not a carved/graven image. It is only a tree. And it does not represent any god like Odin.
Reading a bit of history, the tree started with treats on it, setup for workers or their children to take the treats (apples and candy) before the holiday. This appears to be dated in the 14th-16th centuries. After the Reformation, wealthy Protestants decorated trees in their homes as a replacement for the Catholic nativity scene.
I have said before, that I have an issue with the manger scene as I view that as a graven or molten image and a violation of the commandment while the Christmas tree is not graven or molten and therefore not a violation of the commandment which Jeremiah was referring to.
