The reason why I don't think Aliens from the future...

I know this all theory but someone said it once on here and I took some free time to think about it...


If you look at all the space crafts back then, they where fairly small and all had the same shape, circular... Then they got a cigar shape (around the 70s I believe). Big black triangles in the Belgium wave (1989-90) and now the more recent huge craft, the Phoenix Lights...

Does it seem like they are advancing? A little?

The people from the future can't advance?

They wouldn't go back to the first time that they came back because what's the point of that, they have the info from that time already, so they'd just continue going forwards and advancing as they went.
