What science? So far as I've been able to tell, there's nothing unscientific about interstellar travel, we're constantly evolving our catalog of extrasolar planets ( 890 at last count ), we've got one space probe on the edge of interstellar space now, and there are plenty of concepts for future spacecraft based on real science. Therefore from a scientific perspective, given what we know, the ETH appears to not only be the most reasonable explanation, but it's gaining steam. On the other hand, your assertion is based on mere proclamation. You'll need to do better than that.

Warp Drive May Be More Feasible Than Thought, Scientists Say
"Everything within space is restricted by the speed of light," explained Richard Obousy, president of Icarus Interstellar, a non-profit group of scientists and engineers devoted to pursuing interstellar spaceflight. "But the really cool thing is space-time, the fabric of space, is not limited by the speed of light."
With this concept, the spacecraft would be able to achieve an effective speed of about 10 times the speed of light, all without breaking the cosmic speed limit.
The only problem is, previous studies estimated the warp drive would require a minimum amount of energy about equal to the mass-energy of the planet Jupiter.
But recently White calculated what would happen if the shape of the ring encircling the spacecraft was adjusted into more of a rounded donut, as opposed to a flat ring. He found in that case, the warp drive could be powered by a mass about the size of a spacecraft like the Voyager 1 probe NASA launched in 1977.
Furthermore, if the intensity of the space warps can be oscillated over time, the energy required is reduced even more, White found.
"The findings I presented today change it from impractical to plausible and worth further investigation,"
