He hated him for taking the ring from him
Bilbo Baggins and Gollum first appeared in the hobbit.
In "The Hobbit," Gollum is cunning, with a split personality that fluctuates between his Smeagol and Gollum personas. He is obsessed with the One Ring and is deceitful in his interactions with Bilbo Baggins.
Gollum misunderstood him. Bilbo was saying 'I need more time.' Gollum heard 'time', which was the answer.
Considering that he tries to kill and eat Bilbo in "The Hobbit" and hates Frodo and Sam merely because they are related to Bilbo, I'd say that Gollum doesn't like Bilbo.
Bilbo found both the ring and Gollum.
He would be eaten by Gollum
The company isn't actually all with Gollum, only Bilbo. Bilbo uses the ring he picked up amid his wanderings to escape, which happened to be the one Gollum was looking for. It turns the wearer invisible.
In chapter 5 of The Hobbit by J.R.R. Tolkien, Bilbo escapes from the greedy hands of Gollum. When Gollum realizes that chasing Bilbo is futile, he shouts this last line at Bilbo: "Thief, thief, thief! Baggins! We hates it, we hates it, we hates it for ever!," thus calling Bilbo both 'Thief' and 'Baggins.'
who can really tell? but if gollum had not survived the one ring could never have been destroyed.
It turns the user invisible; Bilbo experienced this firsthand when he escaped the deranged Gollum.
In The Hobbit, Bilbo Baggins joins an adventure along with Gandalf and the dwarf party and takes a ring from Gollum. He then begins a journey with a group of travelers to the Lonely Mountain.
Bilbo said, talking to himself, "what have i got in my pocket?" (it was the Ring). Gollum thought it was a riddle and Bilbo decided to make it one. he gave Gollum three chances to guess and gollum lost after four. then gollum went "to get something" (it was the ring), and Bilbo thought he was abandoned and left with the ring on. Gollum thought Bilbo knew the way out and he wanted to follow him, realizing Bilbo had the ring. Bilbo saw Gollum racing towards the gate and followed him to safety.
