The aliens will live in different regions of the same planets. Thus will coexistence flourish, and when plagues break out, each species will bring in doctors and nurses from an immune species.

Addendum

The same won't be true of the other planets we will undoubtedly colonize because far smaller regions will be inhabited. When you can pick and choose the best places, you don't want to leave anyway.

The Godless City

To remind all men that fortune is never constant, a storm afflicted the victors of the great naval battle so that within an hour they might have wished to have lost it instead that retreat could save them. Of one ship tossed far and then low, sinking, an officer and a portion of his soldiers made the shore.
The officer declared it a miracle and vowed to give offerings to the god who preserved them, and if there was no shrine for the purpose already, he would have one made, and the same for a temple when his means permitted. He encouraged his men to join him in that. "Certainly, but what god is it?" they asked.
The plain and uninhabited shore gave no answer to that. Stymied, the officer led his men away from there and succeeded so well that not a single one of them died before seeing home or whatever other destination he liked.
That duty done, the officer turned to the other, and in furtherance of it he settled a colony where he washed up. It flourished, whereupon the founder attracted scholars and philosophers whom he tasked with determining the god in addition to their other studies.
It flourished still more and soon became prosperous enough that its founder had erected the grandest temple known, though he refused to have it consecrated before his rescuer was known. More than that, he forbade the building of any other temple within the city limits before then. The injunction is observed today. Therefore, stranger, to answer your question at last, your devotions must be done outside the walls.

The Road to Stellar Damascus

"Sir, we landed on the planet for the initial exploration."
"Then why are you here?"
"We saw a man, sir. A human. He told us this. 'Every sun is a god. Worship ours and you will be permitted to live on the surface. To abstain and remain in your generational colony ship, that is permitted as well.'"
"What's this you're telling me?"
"The others will tell you the same, sir. I attempted to initiate diplomacy, but I fell asleep. I woke up on the flight back."
"Absurd."
The captain personally led the second expedition and came back the first priest, and as for the colonists, they learned there was more to space than they dreamed.

Addendum

Is it a ship on a long journey to colonize a distant planet? Is it a traveling casino, circus, or opera house? Does the person one day find himself alone on the ship? It doesn't matter. No, wait, do the circus one.

Addendum

They're gonna need new months! They're gonna have New November and July Alternative!

Cutting Things Into Strips Is a Real Hassle

The king on his proud seat received the colonists who were in his land by no arranged plan but rather by the caprice of gales and crashing waves. He listened to their story and made this response.
"If your bravery will hold for another such voyage, I will feed you and outfit you and send you on your way."
"You are a host among hosts and a king among kings," the colonists said. "Is there meaning though in that 'if?'"
The king called his servants to bring to him a chest, pointed out a great hide within it, and had them offer that to the colonists. "If you seek a sure home, you may find it here under my scepter and laws. You may have for your old customs, your former law, and whatever gods you carried hither just so much as you are able to cover with this mffgh." He shoved off the hide the colonists had thrown over him. "Clever, but to own the king is not to own the kingdom."
"We're gonna make you clean the chamber pots."
"I'll give you one-fifth of my kingdom not to do that."
"Deal!"

Attractions for the Discerning Tourist

When you're in Lonnpor, you can't miss the Red Palace, the Green Palace, or the Glade Festival. Every traveler who does the research finds out about those. But did you know? There's a parade no tourist should ever see. You want to see it now, don't you?
It's called the Emigration Parade, and it's not on a weekly schedule, or monthly, not even yearly. No wonder it isn't as well known as the Devotion of Sixths! No, this parade is held when the city council determines the place is getting a little packed, population-wise. Then it's time for the worst parade!
There's the grand marshal now. Locals recognize him as the guy who stands on street corners and tells you that if you don't like the weather, you should wait a minute! He's waving forward the band. It's not a good band, as expectedwhen the players are those jerks who make a racket in public areas and glare at anyone who passes without dropping a penny. Who do they think they are?
After them come the bakers with their rolling display! A selection of their wares? An oven so the crowd can see them at work? None of that. It's a set of couches they lounge on while fanning themselves with copies of the charter of monopoly the city granted their great-grandfather! There's a reason they all have the same last name, and also a reason their prices are higher than Rellpor's. Try bringing bread from there into the city. They dare you.
Who's that behind him? It's the city's senior judge, who's just dying to handle your suit personally. Why, you'd have to pay him not to! No, really. Pay him. It turns into a real problem if you don't.
After that, the prisoner cart rolls by. Who are those contemptible souls? Murderers? Robbers? People who told tourists about the Emigration Parade and discouraged growth in that vital industry? We won't keep you in suspense: it's the third one.
On and on it goes, each segment designed to remind locals why they've always thought about leaving but never got around to it. Does it work? Just ask the founders of Rellpor, Eckbor, Ptopor, New Lonnpor, Farther Rellpor, Innbor, Tetti Dann Por, Dedvidau, Osspor . . .
