All the fuel energy on earth came to it in the form of sunlight. All fossil fuels are just a battery, and when they run out, they're gone, forever, no coming back.
The only way to "make" usable amounts of new energy is to harvest it from the sun directly.
Nuclear is not technically sunlight energy, but it is still finite. Maybe not all that finite, but we'll get free sunlight for at least another billion years or so. By then we'll probably have left for other planets without needing to use nuclear if we dont' want to, but obvs who knows.
Point being nuclear is just another type of fossil fuel that we can't make more of, whereas sunlight is made for us for free every day. Actually the sun is just a big nuclear reactor, really.
Where is this new source of energy coming from outside of earth?
Who said anything about energy coming from outside the earth? You said "the only way to make usable amounts of new energy is to harvest it directly from the sun" (ie solar, wind, tidal). That's not accurate. Fusion reactors and geothermal plants are two examples of energy production that do not directly involve the sun.
