Raise your script the write way.

It's a fun concept, with two interesting characters, but you lose tension once we find out the aliens are benign. Your two character relationship is the backbone of the story and can be developed more, you can even up the conflict by making them even more different.

So, the script is listed as a comedy, the problem is that it isn’t funny. It has a compelling concept but the pros really end there. So what I most recommend you work on is telling an actually effective story with believable and emotionally compelling characters before adding in a bunch of jokes. Aside from that, you have a few formatting and spelling mistakes all over the place which is also why I recommend reading your script over and out loud. Good luck.
