Firetail you have a point. The Milky Way is a large galaxy, 78 million light years across (which means if you were racing at the speed of light, it would take 78 million years to get from one side of the galaxy to the other). Although we haven't discovered any other planets,there probably are many stars similar to our Sun that have their own Solar System, with planets that are similar to Earth. We would have to know exactly when the sun explodes though, in an estimated 5 billion years, to begin our journey to another solar system.
Don't think anybody mentioned that the moon could alter the rotation of earth's axis, because the moon moves away from the earth a couple inches every year. (eventually there will be no moon in our future!! :O)
Therefore with the gravitation of the moon no longer in effect, waves would cease and the earth would be on an almost endless tumble from being pulled by the sun's, Jupiter's, and other planets gravitation. Water would be pulled to hundreds of miles inward on to 'land' flooding major cities and killing millions. Eventually the magnetic force field surrounding the Earth would be pushed to it's limit and bend and break entirely or be extremely weak and unable to protect the Earth from the suns highly dangerous UV rays. [Earth's magnetic field is weakening, in fact. Should look it up some time ]
Therefore anyone who was out in daylight would face extreme heat, major disease, and will die.( unless they lived underground, but then what about food?)

Keep in mind here that the moon is inching away from the Earth at an astronomically slow pace... the effects on gravitational forces and therefore the tides being determined by the formula:
F = gM1M2/(r^2)
Where g is the gravitational constant that I can never remember, just to get the units all lined up. We can assume for our purposes that the masses of the bodies stay pretty much the same, and r is in metres. As it is, the moon is about, what, 300,000 km away from us, so r is pretty hefty! Two inches a year isn't going to become significant for... quite a while. Something else will probably happen or take effect before then.

I think we already discovered a planet that has water...just not sure if it's hospitable or not.
The earh creates another Earth called E-2 (Sol 3.5) and something on the plants infects the humans and turn them all into zombies and they all starve to death! MUHAHAHAHAHA!
In some time, far from now, the human race will, After a long time of using alternate resources of the earth, will run out of things to give. Then, the humans will have to find somewhere to live, Although Humans will try to survive, the earth itself becomes a dead, lonely wasteland, hosting inhabitants only to the most lowly of creatures.
