Well, if you read the news, you might have seen this item:

A team of scientists has recovered microorganisms in the upper reaches of the atmosphere that could have originated from outer space.
The living bacteria, plucked from an altitude of 10 miles (16 km) or higher by a scientific balloon, could have been deposited in terrestrial airspace by a passing comet, according to the researchers. The microorganisms are unlike any known on Earth.

Note that there may be questions concerning the experiment, but it raises some interesting scientific and theological questions.

Looks like the answer may be yes after all.
