Hazrat adam was a giant?

[Michin Khel]

I have heard that he was 90 feet tall, he died at the age of 913 which is in Quran. Quran also says that hazrat noah preached for 950 years.
So humans were once very tall and used to have life span in centuries?
What does science say about it, any skeletons of giants is found?
