It should surprise you that there is life in even a single one of them, given the standard explanation of things. Here's how you should look at it from that standpoint: The chances that a single celled organism could, through natural selection of random mutations, develop into a world full of life forms such as found here is essentially little different from zero.

The chances that inorganic chemical reactions could result in the formation of a self-replicating single cell are such that, by comparison, the chances that that single cell could result in a world full of life forms such as found here are a dead certainty.

For something like that to happen even a second time you have to have the improbably of the first time squared and so on for each successive time. If life arose here on earth strictly by chance and naturalistic processes, there has not been enough time since the big bang, if there ever was one, or enough places with even near to the right conditions for it to have happened a second time.

All observations, based on a naturalistic scenario, point to the likeliest scenario that we, as sentient beings, are entirely alone in the universe and that we will never find anything even as "simple" (ha ha ha) as a bacterium anywhere else.
