Sorry, but
1. If we can't talk to fish or tulips and they're in our own family tree, then how could we hope to communicate with a lifeform not from this planet?
2. If there is other life and it's interstellar, it may just stripmine and eat or even ranch us, exactly as we have every species we've encountered.
3. 'Terraforming' is ridiculous. We can't even survive (or fix) a 2c shift in a planet we're specifically evolved for, so the chances of survivable conditions elsewhere are exactly zero.
