Ignorance or something else

Hey all, Ive been talkign to my dad about aliens recently not something id normall do and asked if hed believe or if he did. His reply was a genius dave something or other sais that UFO have never been seen entering the atmosphere only traveling within it, this for him is good enogh to believe they are secret techs of our goverment when i showed him gazricks pics he still denied there posibility and sais it was prolly some sort of high tech craft which i find bizare i really disbelief such tech was around but maybe thats what ive been taught to believe by our government.
I also explained some other possibilities such as maybe they travel though dimensions and just turn up here or so advanced we cant detect them - but to that he sais why would they do that then take the trouble to hover over our cities and such - actually he asked why would they dop this at all they obviously dont want to make contact. I gotta say hes made me question myself about my beliefs. My dad is 60 and I think he is a logical thinker - he once seen a ghost but then sais he was sure it was just a trick of the mind - i dunno do you think he might be right, apparently our scanners radar are so powerful we can detect any vessels travelling into our atmosphere accodring to him i cannot varyfy this although it would make sense as to - threat nuclear weapons going into orbit and falling back to earth we must track them somehow.
Im sorry im un a rush writing this gotta pop out just interested in if yiu uys thinhk hes just playing ignorant or he has some valid points.

Ask your father if he truly believes we had a craft in '42 that could fly slowly over a city for an hour, and be immune to over 1400 rounds of AAA fire (while in range of it).

That's what happened in Feb. 1942 over Los Angeles.

My father works on some of the most advanced avionics in the world (the Raptor, for Lockheed). I'd bet dollars to donuts that even now in 2005 we don't have a ship capable of what happened in '42.

I'm not aware of any footage showing any spacecraft of ours entering the atmosphere either. What's that say?
