TIP
Get a telescope. Scan the sky.
One day, aliens could invade Earth. They may be looking
for a new home. They may want to take Earth away from
us. Or they may just want to destroy Earth.
We don’t know what aliens want. We don’t speak their
language. We don’t know anything about them. It will be
hard to win a war against aliens.
Some people think aliens want to turn humans into slaves.
Others think aliens want to kill humans. Either way, we’re
in trouble. Their technology is better than ours.
