The simulations found the opposite: as they travel inward, Hot Jupiters fling rocky debris outward, where it easily clumps into Earth-like planets. Meanwhile, turbulence in clouds slows down small, icy bodies orbiting far off, so they spiral inward and dump water on the young worlds. These can eventually accumulate oceans miles deep and settle into a life-friendly "habitable zone."
"A stunning survey of the latest evidence for intelligent life on Mars. Mac Tonnies brings a thoughtful, balanced and highly accessible approach to one of the most fascinating enigmas of our time."
--Herbie Brennan, author of Martian Genesis and The Atlantis Enigma
"Tonnies drops all predetermined opinions about Mars, and asks us to do the same."
--Greg Bishop, author of Project Beta
"I highly recommend the book for anyone interested in the search for extra-terrestrial artifacts, and the political intrigues that invariably accompany it."
--David Jinks, author of The Monkey and the Tetrahredron
"Mac Tonnies goes where NASA fears to tread and he goes first class."
--Peter Gersten, former Director of Citizens Against UFO Secrecy

Yeah, but isn't part of the problem that, without a "cold Jupiter" like ours to mop up a lot of incoming space rocks, any earthlike worlds that form would be subject to such heavy astroid bombardment that advanced life, at any rate, would likely be wiped out as soon as it evolved?
Advanced life is overrated anyway.
