I think if ET is out there, he’ll have developed far enough to know that whenever a superior species interferes with others, it all goes pear-shaped. It doesn’t matter how well-meaning it is, it alters the balance of nature. We, as humans still are a long way from accepting this, we still introduce species to other continents to eradicate pests and then are surprised when a seemingly unconnected species is wiped out due to the consequences. We’re better off keeping our grubby mitts out, and stop trying to be smarter than Nature, you and i both know it, Humans as a whole don’t.
Therefore, I think that the only time we are going to meet ET is when we rock up to his house in our starship, and that’s a long long way down the road.
Meanwhile, it’s possible that ET is well aware of us, observes us as a long-term science project in action, and is very very careful not to skew it all by letting us see him.
Let’s face it, seeing ET would give a few of the organised religions some headaches explaining these other-worldly beings, and possibly see some of them consigned to the dustbin. Right now, that would seriously screw with ETs project, we’ve almost managed to get off this rock properly yet still are split into deadly divisions over an invisible, unproven Sentient Being who sees ALL of what ALL of us do. If I were ET, I’d be very interested in where this one is going, without messing it up by popping in to say Hi.
Actually, possibly ET might have been screwing with us by putting in a few “flaming chariot” appearances and the like back in history, in the same way bored kids tap on the glass at the aquarium, or simply cannot resist chucking in a piece of bread despite all the “Do NOT feed the animals” signs.
We probably aren’t much of a threat to ET right now, even at our most hostile and aggressive, we’re likely to fizzle out because of it, or because at the other end of the spectrum, we are too nice. I mean, why would any logical species keep the sickly and weak alive? Why pollute the gene pool with those who aren’t healthy? (It’s a little too far for me to say that only the blond haired and blue-eyed Ubermensch should inherit the Earth, but from ET’s point of view, it makes perfect sense, doesn’t it?) I think that we might be able to wring another few millennia out of our time here as ET waits to see how this one pans out - it may be the result of a few Stephen Hawking-like scientists who instruct the physically fit and “healthy” ones how to build our first starship. Now that’s got to be interesting back in ETs lab, hasn’t it, that a “flawed” species may thrive and escape this sphere?
I just hope that ET is more interested in letting us do our own thing, to find our own destiny, rather than him deciding we are out of control and thin us out a bit to re-dress the balance and give all the other creatures here a bit of a chance. If ET likes his project to be manicured like an English country garden, it’s not good for us, the unpredictable stinging creature that might spoil a nice Summer’s day spent sitting and looking at the topiary. And what if ET is a dolphin-like creature, watching in horror at the way we treat members of his evolutionary family?
For me, I think the only other possiblity of seeing ET is when his intergalactic boot stomps us into nothingness, either out of boredom or because we are in the way of the Vogon bulldozers. Even if we developed from the rubbish he threw out of his starship window as he passed by this way billions of years ago, one day there will be a group of convicts wandering by clearing up the litter. I hope they say “Hey, check this out!” when they find us, and don’t just punt us into the furnace to keep this part of the galaxy neat and tidy…
