Aliens as a common occurrence are a big departure from what the Arrowverse has been doing. I mean metahumans were already a pretty big departure between Arrow and The Flash. I am not saying all of this shouldn't be connected or couldn't be merged into one Earth under the right circumstances, but a separate Earth makes a bit more sense.
