.
Atheism merely denotes a lack of belief in God/s and doesn't dictate what else an atheist may or may not believe in. However, I think it unlikely that many atheists would believe in ghosts or Bigfoot. Do you have a source for this claim? Alien life is a different matter. If life can arise on earth, then it seems reasonable to speculate that, given the billions of galaxies endowed with stars having planetary systems that exist in the universe, life must have arisen on some of those planets.

These speculations cannot be compared to a literal acceptance that Noah's flood almost caused the extinction of all terrestrial life on earth a mere four thousand years ago. We know for a fact this didn't happen because the genomes of animals and humans would indicate if they'd suffered a severe population bottleneck in recent history, and they don't. Also, we know it would be impossible to gather together two (or seven) pairs of all terrestrial species and carry them and their food on a boat for seven months. Bear in mind that all the carnivorous animals would require meat, which would mean carrying and feeding huge numbers of their prey species. And a boat that size would have broken up and sank anyway.

..... think of all the systems in the universe ..... the chances are that another planet may support life ..... but I won't believe that until it is proven with evidence that aliens exist.

by even one part in 100,000,000,000,000,000

It's good that you won't believe about life on any planet until there's evidence. Because it looks as if there may be none.....

"The fine-tuning necessary for life to exist on a planet is nothing compared with the fine-tuning required for the universe to exist at all. For example, astrophysicists now know that the values of the four fundamental forces—gravity, the electromagnetic force, and the “strong” and “weak” nuclear forces—were determined less than one millionth of a second after the big bang. Alter any one value and the universe could not exist. For instance, if the ratio between the nuclear strong force and the electromagnetic force had been off by the tiniest fraction of the tiniest fraction—by even one part in 100,000,000,000,000,000—then no stars could have ever formed at all. Feel free to gulp.

Fred Hoyle, the astronomer who coined the term “big bang,” said that his atheism was “greatly shaken” at these developments. He later wrote that “a common-sense interpretation of the facts suggests that a super-intellect has monkeyed with the physics, as well as with chemistry and biology . . . . The numbers one calculates from the facts seem to me so overwhelming as to put this conclusion almost beyond question.”

Theoretical physicist Paul Davies has said that “the appearance of design is overwhelming” and Oxford professor Dr. John Lennox has said “the more we get to know about our universe, the more the hypothesis that there is a Creator . . . gains in credibility as the best explanation of why we are here.”

He likely is but if not then he's definitely delusional.
