As a ratio, based on what "we" have learned ...without looking it up.
I'm curious to see if people know these things.

How did they grow so big?

A lot longer.
Humans have been around for about 250,000 years. I'm not sure about dinosaurs but I would guess about 75 million years |

without looking it up.. about right for humans dinosaurs 160 million |

I remember reading humans and dinosaurs overlapped by about 10000 years. It's astonishing to think they didn't kill us all.

Dinosaurs about 150 million years. First man was created 4026 BC iirc.

is that in the bible  |

So 250,000 vs 160mil... 640 times longer
I was surprised to read we have been around that long. Humans have come a long way since Christ, but Christ what were we doing in the 248,000 years before that? |

''I remember reading humans and dinosaurs overlapped by about 10000 years.''
Where did you read that?! |
|
By:
Dinosaurs were around 140 million years but were extinct before primates appeared 6 million years ago
These evolved to humans around 200000 years ago |

By:
sorry
Primates should read 66 million years |

I would have thought they'd get organised, streamline their activities, invent things sooner.

Pure fiction.

They were organized , for the purpose of hunting , as that was they had to survive on .They invented some better spears ,bows etc to do this .
It was day to day survival , like any other animal . Imagine a caveman who announced he wasn't going to go out hunting that day because he felt there was a better way of surviving and he'd just sit around dreaming up inventions towards that . The other caveman would have said 'wtf you doing' and clubbed him over the head . |

But you can come up with ideas while hunting/ eating etc. 248,000 years!! Our ancestors have a lot to answer for.

In prehistoric times man had technology similar to today often using an animal.For example, photographs were taken with an instant camera, inside the camera box, a bird carved the picture on a stone tablet with its beak. Other commonly used gadgets included a baby woolly mammoth used as a vacuum cleaner; an adult woolly mammoth acting as a shower by spraying water with its trunk; elevators raised and lowered by ropes around brontosauruses' necks; "automatic" windows powered by monkeys on the outside; birds acted as "car horns", sounded by the driver pulling on their tails or squeezing their bodies; a razor made from a clam shell, vibrating from a honey-bee inside; a pelican as a washing machine, shown with a beakful of soapy water; and a woodpecker whose beak was used to play a gramophone record.

Ideas for what
 If they didn't find a large animal (not that easy in a vast wilderness ) and kill it (again very difficult ) and fend off any lions/bears/hyenas that would steal it from them ,then they would starve to death .They were pretty focused on doing this IMO , not daydreaming about things that could not benfit them in anyway . |

[i**** heidelbergensis evolved into **** sapiens approximately 130,000 years ago[/i] So you can shave off 118,000 years |

I do not think that is true Mammals did not really emerge until they were gone, initially things like mice who may have overlapped slightly No humans, except in a few films I have seen |

I have doubts myself about the longevity of the human race
As a species we are unbelievably violent. No other species kills each other as much as we do, I don't think any other species enjoys inflicting pain like we do If you combine that with our cleverness as a species, I think there is a chance we will destroy ourselves |

Dinosaur extinction about 60 million years ago. Humans have only existed a small fraction of that time.

The Chimpanzee are our nearest animal relatives
5 million years separates us, 5 million years ago we were the same animal 3 million years Australopithecus, virtually a Chimpanzee with a straight back all humans come from this..this straight back was important, it allows to voice a large range of sounds necessary for speech 2 million years ago first hominids start to appear, something like us, but with more hair and flat heads Not all hominid species survived, we are the winners The key to our success, our incredible communication ability, this makes us unique, no other animal approaches this. Our brains developed to process this communication, we were able to hold abstract concepts in our minds, we became aware We have also used this brain to understand the world around us, this has enabled us to make our lives more comfortable, discovery of electricity etc |

Some people thi k Dinosurs evolved into Birds
Although the current thinking is they may have both evolved at the same time Recent discoveries in China have found Dinosaur fossils with a covering of feathers So it is possible all Dinosaurs were covered with feathers, although it is doubtful they could fly looking at the size of them The time of the Dinosaurs was followed by a time of large mammals, including large flightless birds Humans have entered the game fairly late on |

The extinction of the Dinosaurs is still a bit of a mystery
A large meteorite did hit the Earth, and there would have been many years of permanent night because of the dust released But it still took over a million years for them to die out...so it is not totally clear Although the meteorite strike would probably have killed off the larger ones... Flora would have suffered and died with no sun the larger herbivores may have become extinct, followed by the larger predators |
