//...on a distant moon.
Europa Clipper will now travel 1.8 billion miles to reach Europa, a deeply mysterious moon orbiting Jupiter.
It will not arrive until 2030 but what it finds could change what we know about life in our solar system.
Trapped under the moon’s surface could be a vast ocean with double the amount of water on Earth.//

Would you like alien life to be discovered - and if not, why not?

For more on marking an answer as the "Best Answer", please visit our FAQ.The only chance we have of any sort of encounter with alien life is from within our solar system and Europa with it's sub ice crust warm ocean is a good candidate. There may well be simple organisms beneath the ice. There are equivalent conditions on earth and life has emerged in them. I think it's a reasonable possibility that it also has under the ice on Europa. I would not like to say I'd like it or not like it just that I understand the possibility.
The Drake equation guarantees nothing. Depending on the inputs (all guesses) fed into the equation, the odds of life elsewhere can vary between next to nothing and near certainty.
There is lots of evidence that things have been seen in our atmosphere which can outmanoeuvre any terrestrial craft, and which can apparently challenge our understanding of gravity and inertia. There could be advanced civilisations which are millions of years ahead of us, and who knows what they might have discovered and invented in all that time?
OG; if they were here they could invade Earth whenever they like, without fear of retaliation. I think it's more likely that they would be neither overtly hostile or friendly, just keeping an eye on us purely out of interest, in case there is anything useful to them in the future. Maybe they could quietly influence a parameter or two so as to encourage our harmless development if we have the potential for that, otherwise to take measures if we seem to be simply too bad stock to hope for a good outcome.

From the above..
//This means there could be as many as two billion Earth-sized planets in the Milky Way galaxy alone, and assuming that all galaxies have number of such planets similar to the Milky Way, in the 50 billion galaxies in the observable universe, there may be as many as a hundred quintillion Earth-like planets.[42] This would correspond to around 20 earth analogs per square centimeter of the Earth.[43]//
I suggest it would be illogical to believe that out of a hundred quintillion earth like planets, no type of life has developed ever developed on any of them - except this one.
