(please say if you are a Human, ghoul, super mutant, or a synth like nick.)

a few hours ago you saw something fall out of the sky and ever since then you've been travelling across the commonwealth to the crash site. You do eventually reach it and see a strange aircraft that you've never seen before. There is a small trail of a green blood-like substance leading away from the crash.

you follow the trail of green blood to a small cave not too far away. You walk inside to see a green humanoid in a weird spacesuit tinkering with a radio. From what you know it looks like something you saw in a comic one time, an alien.

The alien makes a few strange noises before noticing you, it immediately stands up and points it's blaster at you. It then speaks and it's strange speech comes out as English on a translator on it's suit.

???: Halt earthling! Stand still, I won't hesitate to shoot!
