You still misunderstand, I have in fact taken these into account.<quoted text>
You keep saying that distance between galaxies are so vast it's impossible to travel from one to another. Please expand your horizon because only your mentality is one that cannot reach beyond your personal space.
Einstein already came up with wormholes and time travel. There is already the concept of earth energy grid and portals. Open your mind. You said you're open to possibilities but your skepticism proves otherwise.
Time travel won't help very much with distance unless you have a method of traversing great distances to go with it. Wormholes may be possible, only trouble is that calculations so far show that spaghettification is an issue - we'd get squeezed to a pulp just passing through it. They're also pretty hard to find, unless black holes are wormholes at the same time but we'd die passing through it. If other civilizations have mastered interstellar travel they haven't made it here yet.
Heck, it's even possible we're completely surrounded by interstellar timetravellers. It's just they've kept it a secret.
Skepticism is not a bad thing in the face of zero evidence. But that doesn't necessarily mean I'm closed-minded to the possibilities. That's why I've even said from the start that maybe there is a god. It ain't MY fault the fundies can't come up with the goods.(shrug)
