Could Adam have been alive with the dinosaurs according to scripture. Yes, absolutely. No fossils of humans are found with the dinosaurs because humans, Adam and Eve were immortal, they did not die like the animals.
In 7 days God created the Heaven and the Earth. With God a day is 1,000 years, a day is also a day our time. It is ambiguouos whether creation was 7 days our time or 7,000 years. But Man was created immortal, his days were not numbered. There is an indefinite time period between creation and the fall of man, which could have been millions of years. When Adam ate the fruit he became mortal, his days were numbered and time began. God said "In the day they ate of it they would surely die" A day with God is 1,000 years, so they would die within 1,000 years, which accounts for Adam's age of a few hundred years old, from the time of the fall of man until his death.
