As well as occasionally eating each other, we eat a vast selection of the other life on this planet.
We have no qualms about killing these creatures. Hundreds of thousands of birds, fish and animals are killed every day as part of our meat-food supply.
Some we keep as pets and aliens might think these are our emergency food supplies.
I think aliens might ask why we eat flesh when we don't really have to. And why do we eat so much? We could easily live on fruit, vegetables, dairy products and other food types.
I'm not a total vegetarian but it still amazes me how we earth inhabitants eat each other, usually in the dead state and sometimes while still alive.
I think aliens might be quite disgusted with us and could regard us as savages. The fact that we haven't stopped killing one another in wars and disturbances for thousands of years is another minus. Killing seems to be a human trait.
Of course, this is assuming that aliens are vegetarian or have a more civilised system of nutrition. It might be that they are the same as us, or worse. They might even want to eat us.
But just in case they are highly developed, maybe it's time we reviewed our eating habits, cut down on the meat scene and moved more towards vegetables and fruit. Then one day when our out of space visitors arrive in their huge spacecraft they will not completely regard us as cannibals.
On the other hand they may be vegetable life forms themselves and will be totally appalled that we are vegetable eaters. Their word for cannibal would be vegetarian.
It gets so confusing.
One thing's for sure though. If you ever meet an alien the first thing to do is check out what they eat. In the meantime we can all be kind to animals and eat more salads.
