How can 10 points exist in linear order without a first one?

 

Who says they can't.

 In order to count to 10, you have to start at 1.

Its just when they become infinite that there might be ends that don't exist.

 In order to count a countable set, you have to start at 1.

Right, so the countable numbers have ONE end that can be used to count from.
You can count UP to infinity by counting up.
You can't count DOWN from infinity, as there is no place to start.
